Guidance and Manufacturer’s Declaration – Electromagnetic Immunity
The CS CONTROL SYSTEM is intended for use in the electromagnetic environment
specified below. The customer or the end user of the CS CONTROL SYSTEM should assure
it is used in such an environment.

should be used no closer to any
part of the CS CONTROL SYSTEM,
including cables, than the
recommended separation distance
calculated from the equation
applicable to the frequency of the
transmitter.
Recommended separation
distance
d = 1.2√P
d = 1.2√P 80MHz to 800 MHz
d = 2.3√P 800MHz to 2.5GHz
where P is the maximum output
power rating of the transmitter
in watts (W) according to the
transmitter manufacturer and d
is the recommended minimum
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:
Graphic needed.
NOTE 1: At 80MHz and 800MHz, the higher frequency range applies.
NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation is
affected by absorption and reflection from objects, structures 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 CS CONTROL
SYSTEM is used exceeds the applicable RF compliance level above, the CS CONTROL
SYSTEM should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as reorienting or relocating the
CS CONTROL SYSTEM.
b Over the frequency range 150kHz to 80MHz, field strengths should be less than 3V/m.
