Guidance and manufactur er’s declaration – electromagnetic immunity
The 6-series is intended for use in the electromagnetic environment specified below. The customer or the
user of the 6-series 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 6-
series, including cables, than the
recommended separation distance
calculated from the equation applicable
to the frequency of the transmitter.
Recommended separation distance
d = [3,5/3]√ P
d = [3,5/3]√ P 80 MHz to 800 MHz
d = [7/3]√ 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).
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 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 6-series is used exceeds the applicable RF compliance level above, the 6-series
should be observed to verify normal operation. If abnormal performance is observed, additional measures
may be necessary, such as re-orienting or relocating the 6-series.
B Over the frequency range 15 kHz to 8 MHz, field strengths should be less than 3 V / m.
