Guidance and manufacturer's declaration – electromagnetic immunity
The equipment CSPOLA600 is intended for use in the electromagnetic environment specified below. The
customer of the user of the CSPOLA600 should assure that it is used in such an environment.

equipment should not be used close to
any part of the CSPOLA600, including
cables. Recommended separation

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 metres (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
CSPOLA600 is used exceeds the applicable RF compliance level above, CSPOLA600 should be observed to
verify normal operation. If abnormal performance is observed, additional measures may be necessary, such
as re-orienting or relocating CSPOLA600.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
