Guidance and manufacture's declaration – electromagnetic immunity
The BC 57 is intended for use in the electromagnetic environment specified below. The customer or the user of the BC 57 should
assure that it is used in such an environment.

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, ama-
teur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electroma-
gnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength

level
Portable and mobile RF communications equipment should be used no closer to any part
of the BC 57, including cables, than the recommended separation distance calculated
from the equation applicable to the frequency of the transmitter.
Recommended separation distance:
d = 1.2 80 MHz to 800 MHz
d = 2.3 800 MHz to 2.5 GHz
3 V/m
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
a
survey, should be less than the compliance level in each frequency range.
Interference may occur in the vicinity of equipment marked with the following symbol:
