EMC RELATED CAUTION
This equipment and/or system complies with the International Standard IEC 60601-1-2 for electromagnetic
compatibility for medical electrical equipment and/or system. However, an electromagnetic environment that
exceeds the limits or levels stipulated in the IEC 60601-1-2, can cause harmful interference to the equipment
and/or system or cause the equipment and/or system to fail to perform its intended function or degrade its
intended performance. Therefore, during the operation of the equipment and/or system, if there is any
undesired deviation from its intended operational performance, you must avoid, identify and resolve the
adverse electromagnetic effect before continuing to use the equipment and/or system.
The following describes some common interference sources and remedial actions:
1. Strong electromagnetic interference from a nearby emitter source such as an authorized radio station or
cellular phone:
Install the equipment and/or system at another location if it is interfered with by an emitter source such
as an authorized radio station. Keep the emitter source such as cellular phone away from the equipment
and/or system.
2. Radio-frequency interference from other equipment through the AC power supply of the equipment and/
or system:
Identify the cause of this interference and if possible remove this interference source. If this is not
possible, use a different power supply.
3. Effect of direct or indirect electrostatic discharge:
Make sure all users and patients in contact with the equipment and/or system are free from direct or
indirect electrostatic energy before using it. A humid room can help lessen this problem.
4. Electromagnetic interference with any radio wave receiver such as radio or television:
If the equipment and/or system interferes with any radio wave receiver, locate the equipment and/or
system as far as possible from the radio wave receiver.
If the above suggested remedial actions do not solve the problem, consult your Nihon Kohden Corporation
subsidiary or distributor for additional suggestions.
