TABLE 12: 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 that it is used in such an environment.

Intended Electromagnetic
Environment
Portable and mobile RF communications equipment should
be used no closer to any part of the CS CONTROL SYS-
TEM, 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 transmit-
ter 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:
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 compli-
ance 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 re-orienting or relocating the CS CONTROL SYSTEM.
B. Over the frequency range 150kHz to 80MHz, field strengths should be less than 3V/m.
