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.

Safety Information

BEFORE USING THE UNIT, ENSURE THAT AN INTRODUCTION REGARDING THE UNIT FUNCTIONS AND THE SAFETY PRECAUTIONS HAS BEEN PROVIDED BY A PRODUCT REPRESENTATIVE.

CAUTIONS SWITCH THE UNIT OFF BEFORE CLEANING AND DISCONNECT FROM THE MAINS. THE DEVICE MUST ONLY BE OPERATED USING BATTERY POWER IF THE EARTH CONNECTION IS SUSPECT OR IF THE MAINS LEAD IS DAMAGED OR SUSPECTED OF BEING DAMAGED. USE ONLY ACCESSORIES AND OTHER PARTS RECOMMENDED OR SUPPLIED BY SCHILLER AG. USE OF OTHER THAN RECOMMENDED OR SUPPLIED PARTS MAY RESULT IN INJURY INACCURATE INFORMATION AND / OR DAMAGE TO THE UNIT. IT MUST BE ENSURED THAT NEITHER THE PATIENT NOR THE ELECTRODES (INCLUDING THE NEUTRAL ELECTRODE) COME INTO CONTACT WITH OTHER PERSONS OR CONDUCTING OBJECTS (EVEN IF THESE ARE EARTHED). THERE IS NO DANGER WHEN USING THE ECG UNIT FOR A PACEMAKER PATIENT OR WITH SIMULTANEOUS USE OF OTHER ELECTRICAL STIMULATION EQUIPMENT. HOWEVER, THE STIMULATION UNITS SHOULD ONLY BE USED AT A SUFFICIENT DISTANCE FROM THE ELECTRODES. IN CASE OF DOUBT, THE PATIENT SHOULD BE DISCONNECTED FROM THE RECORDER. IF SEVERAL UNITS ARE COUPLED THERE IS A DANGER OF SUMMATION OF LEAKAGE CURRENTS. WHEN OPERATING SEVERAL DEVICES FOR MEDICAL AND NON-MEDICAL APPLICATION DO NOT USE ANY EXTENSION CABLES OR DISTRIBUTION BOXES FOR THE CONNECTION. EARTH MUST BE CONNECTED WHEN THE EXTERNAL PRINTER IS USED.

Introduction The only difference between A tprint is that A ATT-1 and A ATT-1 smar smartprint ATT-1 tprint has a connector for an external ink-jet printer smartprint printer,, which smar makes it possible to generate printouts in A4 size.

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

Automatic Mode a.

without external printer connected or printer switched off

In automatic mode 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

Location & PPower ower 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.

Switching On and Off The AT-1 is switched on with the green ON key and off by means of the red OFF key 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.
