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

Portable and mobile RF communications equipment should be used no closer to any part of this device, including
cables, than the recommended separation distance calculated from the equation applicable to the frequency of the
transmitter.
Recommended separation distance
d = 1,2
d = 1,2
80 MHz to 800 MHz
d = 1,2
800 MHz to 2,5 GHz
where P is the maximum output power rating of the transmitter in watts (W) according to the transmitter manufacturer
and d is the recommended separation distance in metres (m).
Field strengths from fixed RF transmitters, as determined by an electromagnetic site survey,
a should be less than the
compliance level in each frequency range.b
Interference may occur in the vicinity of equipment marked with the following symbol:
NOTE 1 At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects and people.
a 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 this device is used exceeds the applicable
RF compliance level above, this device should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating this device.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
