Guidance and manufacture's declaration – electromagnetic immunity
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios,
a
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 mea-
sured field strength
in the location in which the BC 57 is used exceeds the applicable RF compliance level above, the BC 57 should be observed to
verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or
relocating the BC 57.
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

Recommended separation distances between portable and mobile RF communications equipment and the BC 57
The BC 57 is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The custo-
mer or the user of the BC 57 can help prevent electromagnetic interference by maintaining a minimum distance between por-
table and mobile RF communications equipment (transmitters) and the BC 57 as recommended below, according to the maxi-
mum output power of the communications equipment.
