Guidance and manufacturer's declaration - electromagnetic immunity
The Model CP910E is intended for use in the electromagnetic environment specified below.
The customer or user of the Model CP910E should assure that it is used in such an environment.
Immunity test
Conducted RF
IEC/EN 61000-4-6
Radiated RF
IEC/EN 61000-4-3
NOTE1. At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE2. 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 Model CP910E is used
exceeds the applicable RF compliance level above, the Model CP910E should be observed to
verify normal operation. If abnormal performance is observed, additional measures may be
necessary, such as reorienting or relocating the Model CP910E.
b
Over the frequency range 150 kHz to 80 MHz, field strength should be less than 3 V/m.

Electromagnetic environment - guidance
Portable and mobile RF communications
equipment should be used no closer to
any part of the Model CP910E, including
cables, than the recommended
separation distance calculated from the
equation applicable to frequency of the
transmitter.
Recommended separation distance
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 meters (m).
Field strengths from fixed RF transmitters,
as determined by an electromagnetic site
a
survey,
should be less than the
compliance level in each frequency
b
range.
Interference may occur in the vicinity of
equipment marked with the following
