Power Supply
The mains connection is on the rear of the unit.
The power supply voltage is set by the factory for100-115V(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 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.
Intended Use
The CARDIOVIT AT-2 is a 6-channel ECG recorder with all (12) ECG signals simultaneously processed to provide
instant ECG recordings. Two automatic recording modes can be individually preset to enable one button ECG
recording of preferred print formats.

Introduction
The CARDIOVIT AT-2 is a 6-channel ECG recorder. All ECG signals are simultaneously
processed to provide instant ECG recordings. Two automatic recording modes 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 AT-2 includes the following features:
• Low weight and compact dimensions
• Large A4 size printout from integrated quality thermal printer
• Built-in rechargeable battery for mains-independent use
• Simple one key operation
• Automatic or manual recording modes
• Selectable printing formats

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. The unit should not be operated in areas where
there is any danger of explosion.
Power Supply
The unit can either be operated from the built-in rechargeable battery, or from the mains.
The mains connection is on the rear of the unit. The mains indicator lamp is always lit when
the unit is connected to the mains supply.
A battery indicator lamp confirms battery operation. When the battery capacity is limited, the
indicator flashes. 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 lasts approximately 6 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.

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. The unit should not be operated in areas where
there is any danger of explosion.
Power Supply
The unit can either be operated from the built-in rechargeable battery, or from the mains.
The mains connection is on the rear of the unit. The mains indicator lamp is always lit when
the unit is connected to the mains supply.
A battery indicator lamp confirms battery operation. When the battery capacity is limited, the
indicator flashes. 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 lasts approximately 6 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.

Basic Information
Switching On and Off
The CARDIOVIT AT-2 is switched on by means of the green key and off by means
of the red key.
The unit is 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-2 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 hospital/
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.

General Settings
Each parameter is set by means of a code. This code comprises a combination starting with
the ALT key followed by a number of keys and is always 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 is only released for other functions when the
STOP key is pressed. Once the settings have been confirmed, they are stored in the memory
even when the unit is switched off. As an example, if you want to set the language on your
AT-2 to English, proceed as follows:
