Guidance and manufacturer’s declaration – electromagnetic immunity
The model CL-S200 is intended for use in the electromagnetic environment specified below.
The customer or the user of the model CL-S200 should assure that it is used in such an
environment.
Immunity
IEC 60601 test level
Compliance

Electromagnetic environment
– guidance
Portable and mobile RF
communications equipment should
be used no closer to any part of
the model CL-S200, 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 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 CL-S200 is used
exceeds the applicable RF compliance level above, the model CL-S200 should be observed
to verify normal operation. If abnormal performance is observed, additional measures may be
necessary, such as reorienting or relocating the model CL-S200.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than
3 V/m.
