Guidance and manufacturer's declaration – electromagnetic immunity
The device is intended for use in the electromagnetic environment specified below. The customer or the
user of the device should assure that it is used in such an environment.
Immunity test IEC 60601

IEC 61000-4-3 at 1kHz
NOTE 1 A t 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2 T hese guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects and people.

Field strengths from fixed transmitters, such as base stations for radio (cellular / cordless)
telephones and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast
cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to
fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field
strength in the location in which the device is used exceeds the applicable RF compliance level
above, the device should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as re-orienting or relocating the device.
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3V/m .
