2.2 Warnings
A warning indicates a potentially harmful situation to yourself or
others.
2.2.1 Electric shock hazard
The EVA contains high voltage circuits.
After performing any repair or calibration procedure,
please perform a final electrical safety check and leakage
current test.
Unplug the power cord before cleaning or servicing the
unit. Should the power cord or plug become cracked,
frayed, broken or otherwise damaged, it should be re-
placed immediately.
Do not touch any exposed wiring or conductive surface, while the cover is off and the unit is
energized. When electric power is connected to the EVA, the voltages present can cause in-
jury or death.
Never wear a grounding wrist strap when working on an energized unit. The operator should
not perform any servicing except as specifically stated in the Instruction Manual.
Do not, under any circumstances, perform any testing or maintenance on medical instru-
ments, while they are being used to monitor a patient.
Always turn the EVA
OFF before cleaning.
2.2.2 Explosion hazard
Never use this EVA in the presence of flammable aesthetics.
2.2.3 EMC between EVA and other devices
It is important to install and use the equipment in accordance with the instructions in order
to prevent interference with other devices in the vicinity.
Note that portable and mobile communication equipment can affect medical electrical
equipment.
Interference produced when using the diathermy function may adversely influence the oper-
ation of other electronic equipment.
Failure of the diathermy function may result in an unintended increase of output power.
2.2.4 Safety procedures
This paragraph introduces a few elementary steps to follow when using the Laser Module.
Understanding of these instructions and compliance with them and procedures outlined in
ANSI Standard Z136.3 is required to prevent injury to personnel or damage to the instrument.
