Safety Information

WARNINGS

TO PREVENT ELECTRIC SHOCK DO NOT DISASSEMBLE THE UNIT. NO SERVICEABLE PARTS INSIDE. REFER SERVICING TO QUALIFIED PERSONNEL ONLY.

DO NOT USE THIS UNIT IN AREAS WHERE THERE IS ANY DANGER OF EXPLOSION OR THE PRESENCE OF FLAMMABLE GASES SUCH AS ANAESTHETIC AGENTS.

THIS PRODUCT IS NOT DESIGNED FOR STERILE USE.

THIS PRODUCT IS NOT DESIGNED FOR OUTDOOR USE.

DO NOT, UNDER ANY CIRCUMSTANCES, IMMERSE THE UNIT OR CABLE ASSEMBLIES IN LIQUID.

DO NOT USE HIGH TEMPERATURE STERILISATION PROCESSES (SUCH AS AUTOCLAVING). DO NOT USE E-BEAM OR GAMMA RADIATION STERILISATION.

THIS UNIT IS CF CLASSIFIED ACCORDING TO IEC EN 60601-1. THIS MEANS THAT THE PATIENT CONNECTION IS FULLY ISOLATED AND DEFIBRILLATION PROTECTED. SCHILLER CAN ONLY GUARANTEE PROTECTION AGAINST DEFIBRILLATION VOLTAGE HOWEVER, WHEN THE ORIGINAL SCHILLER PATIENT CABLE IS USED.

DO NOT TOUCH THE CASING DURING DEFIBRILLATION.

IF THE PATIENT CABLE SHOULD BECOME DEFECTIVE AFTER DEFIBRILLATION, LEAD OFF WILL BE DISPLAYED AND AN ACOUSTIC ALARM GIVEN.

The ECG unit is a 3-channel ECG recorder with all (12) ECG signals simultaneously processed to provide instant ECG recordings. Three automatic recording modes — two for the internal printer and one for the external printer — can be individually preset to enable one button ECG recording of preferred print formats.

Individual lamps are provided to give power, paper error, filter, lead group and lead off indications. In addition, any detected disturbance (i.e. loose electrode or end of paper), gives an audible alarm and the corresponding indicator lamp flashes.

The ECG unit includes the following features:

•Low weight and compact dimensions

•Printout from integrated quality thermal printer — OR — from external A4 inkjet printer

•Built-in rechargeable battery for mains-independent use — 2 hours normal use on one battery charge

•Simple one key operation for main functions

•Automatic or manual recording modes

•Selectable printing formats — external and internal printer

•Choice of 10 languages (AT-1) and 9 languages (AT-1 smartprint) for printing.

•Interpretation program option (including measurements) for children and adults

Modes of Operation

Automatic Mode

a.without external printer connected or printer switched off

Automatic Mode provides a printout giving 10 seconds of ECG recording of all 12 leads with a choice of 2 different formats (only for S version).

The following can be programmed freely for each of the 2 formats before recording:

•Lead Format

•Chart Speed

•With the optional interpretation program installed it is also possible to select the measurement table, average cycles with optional markings and interpretation statements for the printout.

For further information see paragraph `Automatic Mode (ECG) Settings` on page 26.

b. with external printer connected and switched on

Only one Automatic Mode format possible. Other details as above.

For further information see paragraph `Automatic Mode (ECG) Settings` on page 30.

•Lead Group

•Chart Speed

•Sensitivity

•Myogram Filter

For further information see paragraph `Manual Mode` on page 8.

Automatic Mode

a.without external printer connected or printer switched off

In automatic mode, a full 12-lead ECG is printed in one of two predefined formats with selectable sensitivity. These formats (see Settings) are selected by the user to suit his specific needs and requirements.

When the AUTO GAIN key is pressed before recording in automatic mode, the unit detects very large waveform amplitudes and sets the sensitivity for the extremity and/or precordial leads accordingly to reduce the overlapping of traces.

To start the automatic ECG recording in Format 1, press the AUTO START key:

To start the automatic recording in Format 2, press the ALT key followed by the AUTO START key:

+

Depending upon which option is included, the printout gives the following:

•ECG recording of all leads in either Standard or Cabrera format according to selection

•Sensitivity

•Heart Rate

Automatic Mode

To obtain an extra printout of the ECG recording in Format 1, simply press the COPY key: To obtain an extra printout of the second format, press the ALT key followed by the COPY key:

‘Automatic Mode (ECG) Settings` on page 26. b. with external printer

With the external printer connected and switched on, only one Auto Mode format (selectable) is available.

To start the automatic ECG recording in Automatic Mode, press the AUTO START key:

For further information see paragraph `Automatic Mode (ECG) Settings` on page 30.

Manual Mode

Manual mode provides a real-time ECG printout of 3 selected leads with full control of parameter selection. This is only possible on the internal thermal printer.

To start the manual recording of a real-time ECG, press the MAN START Printout key

To stop the manual recording (printout) press the STOP key

The printout provides you with the following:

•Three (selected) leads with lead identification.

•On the lower edge, the chart speed and filter settings (if on).

•At the top, the heart rate as current average of 4 beats, trace sensitivity.

The following can be freely chosen during or before the recording:

Location & Power

Location

Do not keep or operate the apparatus in a wet, moist, or dusty environment. Also, avoid exposure to direct sunlight or heat from other sources. Do not allow the unit to come into contact with acidic vapours or liquids, as such contact may cause irreparable damage. The unit should not be placed near X-ray or diathermy units, large transformers or motors. The unit must be placed on a flat surface and must not be operated in areas where there is any danger of explosion.

Power Supply

The mains connection is on the rear of the unit. The mains indicator lamp on the keyboard is always lit when the unit is connected to the mains supply. The unit can either be operated from the mains supply or from the built-in rechargeable battery. The power source is indicated by the respective indicator lamp. When battery capacity is limited, the battery symbol flashes on and off.

To recharge the battery, connect the apparatus to the mains supply by means of the supplied power cable. A totally discharged battery needs less than 15 hours to be fully recharged (60% in less than 3 hours, 90% in less than 7 hours). A fully charged battery gives approximately 2 hours of normal use. The unit can remain connected to the mains supply without any danger of damage to either the battery or the unit.

The unit is automatically switched off after 5 minutes (30 seconds if battery capacity is limited) if no key is pressed and the patient cable is not connected.

Potential Equalisation

If the AT-1 is used in conjunction with other patient connected equipment, we recommend that the potential equalisation stud on the rear of the unit is connected to the building common ground with the yellow/green ground cable (Part-no. 2.310005). When working from an emergency vehicle, the vehicle common ground can be used.

WARNING !

THE UNIT MUST BE GROUNDED WHEN THE EXTERNAL PRINTER IS CONNECTED.

11

Settings

Each parameter is set by means of a code. This code comprises a combination of keys starting with the ALT key followed by two or three numbers. The setting is confirmed with the STOP key. As soon as the ALT key is pressed, the keyboard is dedicated to the programming function.

The setting is remembered and the keyboard released for other functions when the STOP key is pressed. Once a setting has been confirmed, it is stored in the memory even when the unit is switched off.

Example

If you want to set the language on your ECG unit to English, the key sequence given in the table (see page 18), is

ALT — 0 — 2 — 2 — STOP.

On the following pages the programmable parameters and the programming sequences are described in detail.

A printout of the defined settings will be produced and gives the following information, depending on the installed software.

Interpretation Settings (C version only)

The interpretation settings enable the user to determine whether or not certain comments will be added to the interpretation statements on the ECG printout. Furthermore, the patient’s age can be defined (<30 or >30) and if low or high sensitivity should be applied. Low sensitivity will suppress certain non-specific and less important ECG diagnosis; this may be advisable when carrying out ECGs for screening.
