Guidance and manufacturer’s declaration – electromagnetic immunity
The BC 16 is intended for use in the electromagnetic environment specified below. The customer or the user of the BC 16 should assure that it
is used in such an environment.

Portable and mobile RF communications equipment should be used no closer to
any part of the BC 16, including cables, than the recommended separation dis­
tance calculated from the equation applicable to the frequency of the transmitter.
Recommended separation distance:
d = 1.2
d = 1.2 80 MHz to 800 MHz
d = 2.3 800 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).
Field strengths from fixed RF transmitters, as determined by an electromagnetic
site survey, a should be less than the compliance 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 struc­
tures, 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 16 is used exceeds the applicable RF compliance level above, the BC 16 should be observed to verify normal operation. If abnormal per­
formance is observed, additional measures may be necessary, such as re­orienting or relocating the BC 16.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
