Guidance and manufacturer’s declaration – electromagnetic immunity
The BF66 is intended for use in the electromagnetic environment specified below. The customer or the
user of the BF66 should assure that it is used in such an environment.

equipment should be used no closer to any
part of the BF66, including cables, than the
recommended separation distance calcu-
lated from the equation applicable to the fre-
quency of the transmitter.

Where P is the maximum output power rat-
ing of the transmitter in watts (W) accord-

is the recommended separation distance in

Field strengths from fixed RF transmitters,
as determined by an electromagnetic site
survey,
a
should be less than the compli-
ance 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 pre-
dicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF trans-
mitters, an electromagnetic site survey should be considered. If the measured field strength in the
location in which the BF66 is used exceeds the applicable RF compliance level above, the BF66
should be observed to verify normal operation. If abnormal performance is observed, additional mea-
sures may be necessary, such as re-orienting or relocating the BF66.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than [V1] V/m.
