Recommended separation distances between portable and mobile RF communications
equipment and the CS CONTROL SYSTEM.
The CS CONTROL SYSTEM is intended for use in an electromagnetic environment in which
radiated RF disturbances are controlled. The customer or the user of the CS CONTROL
SYSTEM can help prevent electromagnetic interference by maintaining a minimum distance
between the portable and mobile RF communications equipment (transmitters) and the CS
CONTROL SYSTEM as recommended below, according to the maximum output power of
the communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended
separation distance d in meters (m) can be estimated using 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.
NOTE 1: At 80 MHz and 800 MHz, the separation distance for 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.
