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

part of the CIRRUS photo, including cables,
than the recommended separation distance
calculated from the equation applicable to
the frequency of the transmitter.

and d is the recommended separation

Field strengths from fixed RF transmitters
a
should be less than the compliance level b in
each frequency range.
Interference may occur in the vicinity of
equipment marked with the following
symbol:
Note 1: At 80 and 800 MHz, the separation distance of 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
CIRRUS photo is used exceeds the applicable RF
compliance Level above, the CIRRUS photo should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as re-orienting or relocating the CIRRUS photo.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m
