Guidance and manufacturer’s declaration ± electromagnetic immunity
The unit is intended for use in the electromagnetic environment specified below. The customer or the user of the unit
should assure that it is used in such an electromagnetic environment.

Portable and mobile RF communications equipment
should be used no closer to any part of the unit including
cables, than the recommended separation distance
calculated from the equation applicable to the frequency
of the transmitter.

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 meters (m).
Field strengths from fixed RF transmitters, as determined
by an electromagnetic site surveya 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 the unit used exceeds the applicable
RF compliance level above, the unit should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as re-orienting or relocating the unit.
b.
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
