Guidance and manufacturer's declaration
Electromagnetic immunity
The BC 50 is intended for use in the electromagnetic environment specified below. The customer or the user of the BC 50 should assure that it is
used in such an environment.
Immunity test
Conducted RF
IEC 61000-4-6
Radiated RF
IEC 61000-4-3
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 BC 50 is
used exceeds the applicable RF compliance level above, the BC 50 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 50.

Electromagnetic environment - guidance
Portable and mobile RF communications equipment should be
used no closer to any part of the BC 50, including cables, than the
recommended separation distance calculated from the equation
applicable to the frequency of the transmitter.
Recommended separation distance
d=1.2√P
d=1.2√P 80 MHz to 800 MHz
d=2.3√P 800 MHz to 2.5 GHz
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).
