Guidance and manufacturer’s declaration - electromagnetic immunity
The CR-IR 348CL is intended for use in the electromagnetic environment specified below.
The customer or the user of the CR-IR 348CL should assure that it is used in such an environment.
Immunity test

Portable and mobile RF communications
equipment should be used no closer to any part
of the CR-IR 348CL, including cables, than the
recommended separation distance calculated
from the equation applicable to the frequency of
the transmitter.

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 strength 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 CR-IR 348CL is used
exceeds the applicable RF compliance, the CR-IR 348CL should be observed to verify normal operation. If
abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating
the CR-IR 348CL.
b Over the frequency range 150 kHz to 80 MHz, field strength should be less than 3 V/m.
