Guidance and manufacturer’s declaration – electromagnetic immunity
The BG42 is intended for use in the electromagnetic environment specified below. The customer or the
user of the BG42 should assure that it is used in such an environment.

Portable and mobile RF communications
equipment should be used no closer to any
part of the BG42 , including cables, than
the recommended separation distance cal-
culated from the equation applicable to the
frequency of the transmitter.

Field strengths from fixed RF transmitters,
as determined by an electromagnetic site
survey,a should be less than the com-
pliance 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 BG42 is used exceeds the applicable RF compliance level above, the BG42
should be observed to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as re-orienting or relocating the BG42.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than [V1] V/m.
