contours around you.
E-34
Calibrating Direction Readings
You can use the information in this section to calibrate direction readings, which helps
to improve digital compass accuracy.
Direction Reading Calibration Methods
Important!
• To ensure correct direction readings by this watch, be sure to perform bidirectional
calibration before using it. The watch may produce incorrect direction readings if
you do not perform bidirectional calibration.
• Keep the watch away from audio speakers, magnetic necklace, cell phone, and
other devices that generate strong magnetism. Exposure to strong magnetism can
magnetize the watch and cause incorrect direction readings. If incorrect readings
continue even after you perform bidirectional calibration, it could mean that your
watch has been magnetized. If this happens, contact your original retailer or an
authorized CASIO Service Center.
E-35
Bidirectional Calibration
• Use this method when using the watch to take readings in an area where magnetic
force is present, or if you notice that the readings produced by the watch are
different from another compass.
Magnetic Declination Calibration
• You can use this method to specify a magnetic declination value, which sets the
digital compass up to take magnetic north or true north readings.
Precautions about bidirectional calibration
• You can use any two opposing directions for bidirectional calibration. You must,
however, make sure that they are 180 degrees opposite each other. Remember
that if you perform the procedure incorrectly, you will get wrong bearing sensor
readings.
• Do not move the watch while calibration of either direction is in progress.
• You should perform bidirectional calibration in an environment that is the same as
that where you plan to be taking direction readings. If you plan to take direction
readings in an open field, for example, calibrate in an open field.
E-36
To perform bidirectional calibration
1. In the Digital Compass Mode, hold down A for two
seconds.
• This will cause the bidirectional calibration screen to
appear on the digital display.
• The second hand will move to 12 o’clock. This
causes an arrow ( ) symbol to flash on the left
side of the digital display and -1- to be displayed to
indicate that the watch is ready for calibration of the
first direction.
2. Place the watch on a level surface facing any direction
you want, and press B to calibrate the first direction.
• — — — will remain on the digital display while
calibration is in progress. OK will appear when
first direction calibration is complete. About one
second after that, the flashing arrow will change to
point downwards ( ) and -2- will be displayed. This
means that the watch is ready for calibration of the
second direction.
E-37
3. Rotate the watch 180 degrees.
4. Press B again to calibrate the second direction.
• — — — will remain on the digital display while
calibration is in progress. OK will appear when
second direction calibration is complete.
• If ERR appears on the digital display, press B
again to restart calibration.
• Magnetic Declination Correction
With magnetic declination correction, you input a magnetic declination angle
(difference between magnetic north and true north), which allows the watch to
indicate true north. You can perform this procedure when the magnetic declination
angle is indicated on the map you are using. Note that you can input the declination
angle in whole degree units only, so you may need to round off the value specified on
the map. If your map indicates the declination angle as 7.4°, you should input 7°. In
the case of 7.6° input 8°, for 7.5° you can input 7° or 8°.
E-38
To perform magnetic declination correction
1. In the Digital Compass Mode, hold down A for two
seconds.
• This will cause the bidirectional calibration screen
to appear on the digital display.
2. Press C to display the magnetic declination setting
screen (DEC).
3. Use D (East) and B (West) to change the settings.
• The following explains magnetic declination angle
direction settings.
OFF: No magnetic declination correction performed.
The northerly magnetic declination setting
(DEC) will be 0°.

Digital Compass Precautions
Magnetic North and True North
The northerly direction can be expressed either as
magnetic north or true north, which are different from each
other. Also, it is important to keep in mind that magnetic
north moves over time.
• Magnetic north is the north that is indicated by the
needle of a compass.
• True north, which is the location of the North Pole of the
Earth’s axis, is the north that is normally indicated on
maps.
• The difference between magnetic north and true north
is called the “declination”. The closer you get to the
North Pole, the greater the declination angle.

E-41
Location
• Taking a direction reading when you are near a source of strong magnetism can
cause large errors in readings. Because of this, you should avoid taking direction
readings while in the vicinity of the following types of objects: permanent magnets
(magnetic necklaces, etc.), concentrations of metal (metal doors, lockers, etc.),
high tension wires, aerial wires, household appliances (TVs, personal computers,
washing machines, freezers, etc.).
• Accurate direction readings are impossible while in a train, boat, air plane, etc.
• Accurate readings are also impossible indoors, especially inside ferroconcrete
structures. This is because the metal framework of such structures picks up
magnetism from appliances, etc.
E-42
Storage
• The precision of the bearing sensor may deteriorate if the watch becomes
magnetized. Because of this, you should store the watch away from magnets or any
other sources of strong magnetism, including: permanent magnets (magnetic
necklaces, etc.) and household appliances (TVs, personal computers, washing
machines, freezers, etc.).
• Whenever you suspect that the watch may have become magnetized, perform the
procedure under “To perform bidirectional calibration” (page E-36).
E-43
Thermometer

To enter and exit the Thermometer Mode
1. In the Timekeeping Mode or Digital Compass Mode,
press D.
• THERMO will appear on the digital display for about
one second indicating that temperature readings
are being taken. After that, the measurement result
will appear.
• The watch will take temperature readings every five
seconds for one or two minutes.
• To restart temperature readings, press D.
2. Press C to return to the Timekeeping Mode.
• If you do not perform any button operation for one
or two minutes after temperature measurement is
complete, the watch will automatically return to the
Timekeeping Mode.

Temperature
• Temperature is displayed in units of 0.1°C (or 0.2°F).
• The displayed temperature value changes to —.- °C (or °F) if a measured
temperature falls outside the range of –10.0°C to 60.0°C (14.0°F to 140.0°F). The
temperature value will reappear as soon as the measured temperature is within the
allowable range.
Display Units
You can select either Celsius (°C) or Fahrenheit (°F) for the displayed temperature
value. See “To specify temperature unit” (page E-47) for more information.
Temperature Sensor Calibration
The watch’s temperature sensor is calibrated at the factory and normally requires no
further adjustment. If you notice serious errors in the temperature readings produced
by the watch, you can calibrate the sensor to correct the errors.
E-45
Important!
• Incorrectly calibrating the temperature sensor can result in incorrect readings.
Carefully read the following before doing anything.
– Compare the readings produced by the watch with those of another reliable and
accurate thermometer.
– If adjustment is required, remove the watch from your wrist and wait for 20 or 30
minutes to give the temperature of the watch time to stabilize.
To correct the temperature value
You can correct the temperature readings displayed by
the watch in accordance with another measuring
instrument for more accurate readings.
1. In the Thermometer Mode, hold down A until the
current temperature value flashes on the digital display.
This is the setting screen.
E-46
2. Use D (+) and B (–) to calibrate the temperature value with the reading of another
instrument.
• Each press of a button changes the temperature value in units of 0.1°C (0.2°F).
• To return the currently flashing value to its initial factory default setting, press
B and D at the same time. OFF will appear at the flashing location for about
one second, followed by the initial default value.
3. Press A to return to the Thermometer Mode.
Thermometer Precautions
• Temperature measurements are affected by your body temperature (while you are
wearing the watch), direct sunlight, and moisture. To achieve a more accurate
temperature measurement, remove the watch from your wrist, place it in a well
ventilated location out of direct sunlight, and wipe all moisture from the case. It
takes approximately 20 to 30 minutes for the case of the watch to reach the actual
surrounding temperature.
• When taking temperature readings, it is best to remove the watch from your wrist in
order to eliminate the effects of body heat. Remove the watch from your wrist and
allow it to hang freely from your bag or in another location where it is not exposed
to direct sunlight.

Troubleshooting
Time Setting
■ Why is the current time setting off by a couple of hours?
Your Home City setting may be wrong (page E-17). Check your Home City setting and
correct it, if necessary.
■ Why is the current time setting off by one hour?
You may need to change your Home City’s standard time/daylight saving time (DST)
setting. Use the procedure under “To change the current time and date settings” (page
E-22) to change the standard time/daylight saving time (DST) setting.
Sensor modes
■ Why can’t I change the temperature unit setting?
The temperature unit setting is always Celsius (°C) whenever TOKYO is selected as
the Home City. In this case, the setting cannot be changed.
E-71
■ Why does “ERR” appear while a sensor operation is in progress?
Subjecting the watch to strong impact can cause sensor malfunction or improper
contact of internal circuitry. When this happens, ERR (error) will appear on the digital
display and sensor operations will be disabled.
Direction Reading and
Temperature Measurement
• If ERR appears while a measurement operation is being performed in a sensor
mode, restart the measurement. If ERR appears on the digital display again, it can
mean there is something wrong with the sensor.
• If ERR keeps appearing during measurement, it can mean there is a problem with
the applicable sensor.
E-72
■ Why does “ERR” appear on the digital display following bidirectional
calibration?
If — — — appears and then changes to ERR (error) on the calibration screen, it means
that there is something wrong with the sensor.
• If ERR disappears after about one second, try performing the calibration again.
• If ERR keeps appearing, contact your original dealer or nearest authorized CASIO
distributor to have the watch checked.
Whenever you have a sensor malfunction, take the watch to your original dealer or
nearest authorized CASIO distributor as soon as possible.
■ What causes incorrect direction readings?
• Incorrect bidirectional calibration. Perform bidirectional calibration (page E-36).
• Nearby source of strong magnetism, such as a household appliance, a large steel
bridge, a steel beam, overhead wires, etc., or an attempt to perform direction
measurement on a train, boat, etc. Move away from large metal objects and try
again.
E-73
■ What causes different direction readings to produce different results at the
same location?
Magnetism generated by nearby high-tension wires is interfering with detection of
terrestrial magnetism. Move away from the high-tension wires and try again.
■ Why am I having problems taking direction readings indoors?
A TV, personal computer, speakers, or some other object is interfering with terrestrial
magnetism readings. Move away from the object causing the interference or take the
direction reading outdoors. Indoor direction readings are particularly difficult inside
ferro-concrete structures. Remember that you will not be able to take direction
readings inside of trains, airplanes, etc.
E-74
Battery
■ Why is the low battery alert flashing?
Battery power is low. Watch operations are disabled while
the low battery alert is flashing on the digital display.
If the low battery alert disappears after battery power
recovers but then starts to flash again after a short while,
it means that you need to have the watch’s battery
replaced.

3. Determine your location and destination by checking the map and the geographic
contours around you.
E-34
Calibrating Direction Readings
You can use the information in this section to calibrate direction readings, which helps
to improve digital compass accuracy.
Direction Reading Calibration Methods
Important!
• To ensure correct direction readings by this watch, be sure to perform bidirectional
calibration before using it. The watch may produce incorrect direction readings if
you do not perform bidirectional calibration.
• Keep the watch away from audio speakers, magnetic necklace, cell phone, and
other devices that generate strong magnetism. Exposure to strong magnetism can
magnetize the watch and cause incorrect direction readings. If incorrect readings
continue even after you perform bidirectional calibration, it could mean that your
watch has been magnetized. If this happens, contact your original retailer or an
authorized CASIO Service Center.
E-35
Bidirectional Calibration
• Use this method when using the watch to take readings in an area where magnetic
force is present, or if you notice that the readings produced by the watch are
different from another compass.
Magnetic Declination Calibration
• You can use this method to specify a magnetic declination value, which sets the
digital compass up to take magnetic north or true north readings.
Precautions about bidirectional calibration
• You can use any two opposing directions for bidirectional calibration. You must,
however, make sure that they are 180 degrees opposite each other. Remember
that if you perform the procedure incorrectly, you will get wrong bearing sensor
readings.
• Do not move the watch while calibration of either direction is in progress.
• You should perform bidirectional calibration in an environment that is the same as
that where you plan to be taking direction readings. If you plan to take direction
readings in an open field, for example, calibrate in an open field.
E-36
To perform bidirectional calibration
1. In the Digital Compass Mode, hold down A for two
seconds.
• This will cause the bidirectional calibration screen to
appear on the digital display.
• The second hand will move to 12 o’clock. This
causes an arrow ( ) symbol to flash on the left
side of the digital display and -1- to be displayed to
indicate that the watch is ready for calibration of the
first direction.
2. Place the watch on a level surface facing any direction
you want, and press B to calibrate the first direction.
• — — — will remain on the digital display while
calibration is in progress. OK will appear when
first direction calibration is complete. About one
second after that, the flashing arrow will change to
point downwards ( ) and -2- will be displayed. This
means that the watch is ready for calibration of the
second direction.
E-37
3. Rotate the watch 180 degrees.
4. Press B again to calibrate the second direction.
• — — — will remain on the digital display while
calibration is in progress. OK will appear when
second direction calibration is complete.
• If ERR appears on the digital display, press B
again to restart calibration.
• Magnetic Declination Correction
With magnetic declination correction, you input a magnetic declination angle
(difference between magnetic north and true north), which allows the watch to
indicate true north. You can perform this procedure when the magnetic declination
angle is indicated on the map you are using. Note that you can input the declination
angle in whole degree units only, so you may need to round off the value specified on
the map. If your map indicates the declination angle as 7.4°, you should input 7°. In
the case of 7.6° input 8°, for 7.5° you can input 7° or 8°.
E-38
To perform magnetic declination correction
1. In the Digital Compass Mode, hold down A for two
seconds.
• This will cause the bidirectional calibration screen
to appear on the digital display.
2. Press C to display the magnetic declination setting
screen (DEC).
3. Use D (East) and B (West) to change the settings.
• The following explains magnetic declination angle
direction settings.
OFF: No magnetic declination correction performed.
The northerly magnetic declination setting
(DEC) will be 0°.

Digital Compass Precautions
Magnetic North and True North
The northerly direction can be expressed either as
magnetic north or true north, which are different from each
other. Also, it is important to keep in mind that magnetic
north moves over time.
• Magnetic north is the north that is indicated by the
needle of a compass.
• True north, which is the location of the North Pole of the
Earth’s axis, is the north that is normally indicated on
maps.
• The difference between magnetic north and true north
is called the “declination”. The closer you get to the
North Pole, the greater the declination angle.
True north
Earth

Magnetic north
E-41
Location
• Taking a direction reading when you are near a source of strong magnetism can
cause large errors in readings. Because of this, you should avoid taking direction
readings while in the vicinity of the following types of objects: permanent magnets
(magnetic necklaces, etc.), concentrations of metal (metal doors, lockers, etc.),
high tension wires, aerial wires, household appliances (TVs, personal computers,
washing machines, freezers, etc.).
• Accurate direction readings are impossible while in a train, boat, air plane, etc.
• Accurate readings are also impossible indoors, especially inside ferroconcrete
structures. This is because the metal framework of such structures picks up
magnetism from appliances, etc.
E-42
Storage
• The precision of the bearing sensor may deteriorate if the watch becomes
magnetized. Because of this, you should store the watch away from magnets or any
other sources of strong magnetism, including: permanent magnets (magnetic
necklaces, etc.) and household appliances (TVs, personal computers, washing
machines, freezers, etc.).
• Whenever you suspect that the watch may have become magnetized, perform the
procedure under “To perform bidirectional calibration” (page E-36).
E-43

Temperature Sensor Calibration
The watch’s temperature sensor is calibrated at the factory and normally requires no
further adjustment. If you notice serious errors in the temperature readings produced
by the watch, you can calibrate the sensor to correct the errors.
E-45
Important!
• Incorrectly calibrating the temperature sensor can result in incorrect readings.
Carefully read the following before doing anything.
– Compare the readings produced by the watch with those of another reliable and
accurate thermometer.
– If adjustment is required, remove the watch from your wrist and wait for 20 or 30
minutes to give the temperature of the watch time to stabilize.
To correct the temperature value
You can correct the temperature readings displayed by
the watch in accordance with another measuring
instrument for more accurate readings.
1. In the Thermometer Mode, hold down A until the

Troubleshooting
Time Setting
■ Why is the current time setting off by a couple of hours?
Your Home City setting may be wrong (page E-17). Check your Home City setting and
correct it, if necessary.
■ Why is the current time setting off by one hour?
You may need to change your Home City’s standard time/daylight saving time (DST)
setting. Use the procedure under “To change the current time and date settings” (page
E-22) to change the standard time/daylight saving time (DST) setting.
Sensor modes
■ Why can’t I change the temperature unit setting?
The temperature unit setting is always Celsius (°C) whenever TOKYO is selected as
the Home City. In this case, the setting cannot be changed.
E-71
■ Why does “ERR” appear while a sensor operation is in progress?
Subjecting the watch to strong impact can cause sensor malfunction or improper
contact of internal circuitry. When this happens, ERR (error) will appear on the digital
display and sensor operations will be disabled.
Direction Reading and
Temperature Measurement
• If ERR appears while a measurement operation is being performed in a sensor
mode, restart the measurement. If ERR appears on the digital display again, it can
mean there is something wrong with the sensor.
• If ERR keeps appearing during measurement, it can mean there is a problem with
the applicable sensor.
E-72
■ Why does “ERR” appear on the digital display following bidirectional
calibration?
If — — — appears and then changes to ERR (error) on the calibration screen, it means
that there is something wrong with the sensor.
• If ERR disappears after about one second, try performing the calibration again.
• If ERR keeps appearing, contact your original dealer or nearest authorized CASIO
distributor to have the watch checked.
Whenever you have a sensor malfunction, take the watch to your original dealer or
nearest authorized CASIO distributor as soon as possible.
■ What causes incorrect direction readings?
• Incorrect bidirectional calibration. Perform bidirectional calibration (page E-36).
• Nearby source of strong magnetism, such as a household appliance, a large steel
bridge, a steel beam, overhead wires, etc., or an attempt to perform direction
measurement on a train, boat, etc. Move away from large metal objects and try
again.
E-73
■ What causes different direction readings to produce different results at the
same location?
Magnetism generated by nearby high-tension wires is interfering with detection of
terrestrial magnetism. Move away from the high-tension wires and try again.
■ Why am I having problems taking direction readings indoors?
A TV, personal computer, speakers, or some other object is interfering with terrestrial
magnetism readings. Move away from the object causing the interference or take the
direction reading outdoors. Indoor direction readings are particularly difficult inside
ferro-concrete structures. Remember that you will not be able to take direction
readings inside of trains, airplanes, etc.
E-74
Battery
■ Why is the low battery alert flashing?
Battery power is low. Watch operations are disabled while
the low battery alert is flashing on the digital display.
If the low battery alert disappears after battery power
recovers but then starts to flash again after a short while,
it means that you need to have the watch’s battery
replaced.

E-34
Calibrating Direction Readings
You can use the information in this section to calibrate direction readings, which helps
to improve digital compass accuracy.
Direction Reading Calibration Methods
Important!
• To ensure correct direction readings by this watch, be sure to perform bidirectional
calibration before using it. The watch may produce incorrect direction readings if
you do not perform bidirectional calibration.
• Keep the watch away from audio speakers, magnetic necklace, cell phone, and
other devices that generate strong magnetism. Exposure to strong magnetism can
magnetize the watch and cause incorrect direction readings. If incorrect readings
continue even after you perform bidirectional calibration, it could mean that your
watch has been magnetized. If this happens, contact your original retailer or an
authorized CASIO Service Center.
E-35
Bidirectional Calibration
• Use this method when using the watch to take readings in an area where magnetic
force is present, or if you notice that the readings produced by the watch are
different from another compass.
Magnetic Declination Calibration
• You can use this method to specify a magnetic declination value, which sets the
digital compass up to take magnetic north or true north readings.
Precautions about bidirectional calibration
• You can use any two opposing directions for bidirectional calibration. You must,
however, make sure that they are 180 degrees opposite each other. Remember
that if you perform the procedure incorrectly, you will get wrong bearing sensor
readings.
• Do not move the watch while calibration of either direction is in progress.
• You should perform bidirectional calibration in an environment that is the same as
that where you plan to be taking direction readings. If you plan to take direction
readings in an open field, for example, calibrate in an open field.
E-36
To perform bidirectional calibration
1. In the Digital Compass Mode, hold down A for two
seconds.
• This will cause the bidirectional calibration screen to
appear on the digital display.
• The second hand will move to 12 o’clock. This
causes an arrow ( ) symbol to flash on the left
side of the digital display and -1- to be displayed to
indicate that the watch is ready for calibration of the
first direction.
2. Place the watch on a level surface facing any direction
you want, and press B to calibrate the first direction.
• — — — will remain on the digital display while
calibration is in progress. OK will appear when
first direction calibration is complete. About one
second after that, the flashing arrow will change to
point downwards ( ) and -2- will be displayed. This
means that the watch is ready for calibration of the
second direction.
E-37
3. Rotate the watch 180 degrees.
4. Press B again to calibrate the second direction.
• — — — will remain on the digital display while
calibration is in progress. OK will appear when
second direction calibration is complete.
• If ERR appears on the digital display, press B
again to restart calibration.
• Magnetic Declination Correction
With magnetic declination correction, you input a magnetic declination angle
(difference between magnetic north and true north), which allows the watch to
indicate true north. You can perform this procedure when the magnetic declination
angle is indicated on the map you are using. Note that you can input the declination
angle in whole degree units only, so you may need to round off the value specified on
the map. If your map indicates the declination angle as 7.4°, you should input 7°. In
the case of 7.6° input 8°, for 7.5° you can input 7° or 8°.
E-38
To perform magnetic declination correction
1. In the Digital Compass Mode, hold down A for two
seconds.
• This will cause the bidirectional calibration screen
to appear on the digital display.
2. Press C to display the magnetic declination setting
screen (DEC).
3. Use D (East) and B (West) to change the settings.
• The following explains magnetic declination angle
direction settings.
OFF: No magnetic declination correction performed.
The northerly magnetic declination setting
(DEC) will be 0°.

Digital Compass Precautions
Magnetic North and True North
The northerly direction can be expressed either as
magnetic north or true north, which are different from each
other. Also, it is important to keep in mind that magnetic
north moves over time.
• Magnetic north is the north that is indicated by the
needle of a compass.
• True north, which is the location of the North Pole of the
Earth’s axis, is the north that is normally indicated on
maps.
• The difference between magnetic north and true north
is called the “declination”. The closer you get to the
North Pole, the greater the declination angle.

E-41
Location
• Taking a direction reading when you are near a source of strong magnetism can
cause large errors in readings. Because of this, you should avoid taking direction
readings while in the vicinity of the following types of objects: permanent magnets
(magnetic necklaces, etc.), concentrations of metal (metal doors, lockers, etc.),
high tension wires, aerial wires, household appliances (TVs, personal computers,
washing machines, freezers, etc.).
• Accurate direction readings are impossible while in a train, boat, air plane, etc.
• Accurate readings are also impossible indoors, especially inside ferroconcrete
structures. This is because the metal framework of such structures picks up
magnetism from appliances, etc.
E-42
Storage
• The precision of the bearing sensor may deteriorate if the watch becomes
magnetized. Because of this, you should store the watch away from magnets or any
other sources of strong magnetism, including: permanent magnets (magnetic
necklaces, etc.) and household appliances (TVs, personal computers, washing
machines, freezers, etc.).
• Whenever you suspect that the watch may have become magnetized, perform the
procedure under “To perform bidirectional calibration” (page E-36).
E-43

Temperature Sensor Calibration
The watch’s temperature sensor is calibrated at the factory and normally requires no
further adjustment. If you notice serious errors in the temperature readings produced
by the watch, you can calibrate the sensor to correct the errors.
E-45
Important!
• Incorrectly calibrating the temperature sensor can result in incorrect readings.
Carefully read the following before doing anything.
– Compare the readings produced by the watch with those of another reliable and
accurate thermometer.
– If adjustment is required, remove the watch from your wrist and wait for 20 or 30
minutes to give the temperature of the watch time to stabilize.
To correct the temperature value
You can correct the temperature readings displayed by
the watch in accordance with another measuring
instrument for more accurate readings.
1. In the Thermometer Mode, hold down A until the

correct it, if necessary.
■ Why is the current time setting off by one hour?
You may need to change your Home City’s standard time/daylight saving time (DST)
setting. Use the procedure under “To change the current time and date settings” (page
E-22) to change the standard time/daylight saving time (DST) setting.
Sensor modes
■ Why can’t I change the temperature unit setting?
The temperature unit setting is always Celsius (°C) whenever TOKYO is selected as
the Home City. In this case, the setting cannot be changed.
E-71
■ Why does “ERR” appear while a sensor operation is in progress?
Subjecting the watch to strong impact can cause sensor malfunction or improper
contact of internal circuitry. When this happens, ERR (error) will appear on the digital
display and sensor operations will be disabled.
Direction Reading and
Temperature Measurement
• If ERR appears while a measurement operation is being performed in a sensor
mode, restart the measurement. If ERR appears on the digital display again, it can
mean there is something wrong with the sensor.
• If ERR keeps appearing during measurement, it can mean there is a problem with
the applicable sensor.
E-72
■ Why does “ERR” appear on the digital display following bidirectional
calibration?
If — — — appears and then changes to ERR (error) on the calibration screen, it means
that there is something wrong with the sensor.
• If ERR disappears after about one second, try performing the calibration again.
• If ERR keeps appearing, contact your original dealer or nearest authorized CASIO
distributor to have the watch checked.
Whenever you have a sensor malfunction, take the watch to your original dealer or
nearest authorized CASIO distributor as soon as possible.
■ What causes incorrect direction readings?
• Incorrect bidirectional calibration. Perform bidirectional calibration (page E-36).
• Nearby source of strong magnetism, such as a household appliance, a large steel
bridge, a steel beam, overhead wires, etc., or an attempt to perform direction
measurement on a train, boat, etc. Move away from large metal objects and try
again.
E-73
■ What causes different direction readings to produce different results at the
same location?
Magnetism generated by nearby high-tension wires is interfering with detection of
terrestrial magnetism. Move away from the high-tension wires and try again.
■ Why am I having problems taking direction readings indoors?
A TV, personal computer, speakers, or some other object is interfering with terrestrial
magnetism readings. Move away from the object causing the interference or take the
direction reading outdoors. Indoor direction readings are particularly difficult inside
ferro-concrete structures. Remember that you will not be able to take direction
readings inside of trains, airplanes, etc.
E-74
Battery
■ Why is the low battery alert flashing?
Battery power is low. Watch operations are disabled while
the low battery alert is flashing on the digital display.
If the low battery alert disappears after battery power
recovers but then starts to flash again after a short while,
it means that you need to have the watch’s battery
replaced.
