Guidance and manufacturer's declaration - electromagnetic immunity
The BG5S is intended for use in the electromagnetic environment specified below. The customer or the user
of the BG5S should assure that it is used in such an environment.

Conducted RF 3 Vrms 150 kHz
IEC 61000-4-6 to 80 MHz
Radiated RF 3 V/m 80 MHz to
IEC 61000-4-3 2,5 GHz
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
BG5S is used exceeds the applicable RF compliance level above, the BG5S should be observed to verify
normal operation. If abnormal performance is observed, additional measures may be necessary, such as
re-orienting or relocating the BG5S.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3V/m.
