EMC RELATED CAUTION
This equipment and/or system complies with IEC 60601-2 International
Standard for electromagnetic compatibility for medical electrical equipment
and/or system. However, an electromagnetic environment that exceeds the
limits or levels stipulated in 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. Keep the emitter
source such as cellular phone away from the equipment and/or system, or
turn off the cellular phone.
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.
