Care & Maintenance
12 Monthly Check
The unit should undergo a technical safety check every 12 months. This safety check should
include the following:

• Electrical safety tests according to IEC 601-1 and IEC 601-2-25.
• Functional tests according to the Service Handbook.
The test results must be documented.
Cleaning the Casing
CAUTION
SWITCH THE UNIT OFF BEFORE CLEANING AND DISCONNECT THE MAINS. DO
NOT, UNDER ANY CIRCUMSTANCES, IMMERSE THE APPARATUS INTO A
CLEANING LIQUID OR STERILIZE WITH HOT WATER, STEAM, OR AIR.
The casing of the AT-2 can be cleaned with a soft damp cloth on the surface only. Where necessary
a domestic non-caustic cleaner can be used for grease and finger marks.
Cleaning the Patient Cable
CAUTION
ALIGN THE LEADS IN SUCH A WAY AS TO PREVENT ANYONE STUMBLING OVER
THEM OR ANY DAMAGE CAUSED BY THE WHEELS OF INSTRUMENT TROLLEYS.
The patient cable should not be exposed to excessive mechanical stress. Whenever disconnecting
the leads, hold the plugs and not the cables. Store the leads in such a way as to prevent anyone
stumbling over them or any damage being caused by the wheels of instrument trolleys.
The cable can be wiped with soapy water. Sterilization, if required, should be done with gas only
and not with steam. To disinfect, wipe the cable with hospital standard disinfectant.
Cleaning the Thermal Print Head
If the printer is used a lot, a residue of printers ink ( from the grid on the paper) can build up on the
print head. This can cause the print quality to deteriorate. We recommend therefore that every
month the print head is cleansed with alcohol as follows:
Remove the paper tray. The thermal printhead is found under the paper tray release catch. With a
tissue dampened in alcohol, gently rub the printhead to remove the ink residue. If the printhead is
badly soiled, the colour of the paper grid ink (i.e. red or green) will show on the tissue.
