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:
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.

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.

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.

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 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.
5. Interference of lightning
When lightning occurs near the location where the equipment and/or system is
installed, it may induce an excessive voltage in the equipment and/or system.
In such a case, disconnect the AC power cord from the equipment and/or
system and operate the equipment and/or system by battery power, or use an
uninterruptible power supply.
