Disposal Instructions and Battery Care

° DO NOT DISPOSE OF THE BATTERY BY FIRE OR INCINERATOR - DANGER OF

EXPLOSION ° DO NOT ATTEMPT TO RECHARGE THE BATTERY - DANGER OF EXPLOSION ° DO NOT OPEN THE BATTERY CASING - DANGER OF ACID BURN

Only dispose of the battery in official recycling centres or municipally approved areas. Alternatively, used batteries can be returned to SCHILLER AG for disposal.

Unit Disposal Instructions

Units no longer required can be returned to SCHILLER AG for disposal. Alternatively dispose of the unit in municipally approved recycling centres.

This equipment has been tested and found to comply with the limits for a class A digital device, pursuant to both Part 15 of the FCC (Federal Communications Commission) Rules and the radio interference regulations of the Canadian Department of Communications. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with this instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to

correct the interference at his own expense.

Important Information

Power Supply

The mains connection is on the rear of the unit.

The power supply voltage is set by the factory for 100-115V (nom. 110V) or 220-240V (nom. 230V) working. The setting is indicated by the indented metal strip on the fuse panel. Contact your dealer if the voltage needs to be changed.

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.

Changing a Mains Fuse

If it is necessary to change a fuse, always replace with the correct rating i.e. 2x200mAT for 230V, or 2x315mAT for 110V.

To change a fuse press the two retaining lugs on the side of the fuse panel (situated below the mains connector on the back panel). Remove the fuse panel and replace the fuse(s). Click back the fuse panel.

NOTE:NOTE:

NOTE:

NOTE:NOTE:

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

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.
