Guidance and manufacturer’s declaration – electromagnetic immunity
The BG 51 is intended for use in the electromagnetic environment specified below. The customer or the user
of the BG 51 should assure that it is used in such an environment.

Portable and mobile RF communications equip-
ment should be used no closer to any part of
the BG 51, including cables, than the recom-
mended separation distance calculated from
the equation applicable to the frequency of the
transmitter.

P
is the maximum output power rating
of the transmitter in watts (W) according to the
transmitter manufacturer and
d

Field strengths from fixed RF transmitters, as
determined by an electromagnetic site survey,

should be less than the compliance level in
each frequency range.
b
Interference may occur in the vicinity of equip-
ment 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 absorp-
tion 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 the-
oretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an elec-
tromagnetic site survey should be considered. If the measured field strength in the location in which the
BG 51 is used exceeds the applicable RF compliance level above, the BG 51 should be observed to verify
normal operation. If abnormal performance is observed, additional measures may be necessary, such as
re-orienting or relocating the BG 51.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than [V1] V/m.
