Recommended separation distances between portable and mobile RF communications
equipment and the
AutoSet CS2
The AutoSet CS2 is intended for use in an environment in which radiated RF disturbances are controlled. The
customer or the user of the AutoSet CS2 can help prevent electromagnetic interference by maintaining a
minimum distance between portable and mobile RF communications equipment (transmitters) and the AutoSet
CS2 as recommended below, according to the maximum output power of the communications equipment.

100 11.70 3.50 7.00
For transmitters rated at a maximum output power not listed above, the recommended separation distance d in
metres (m) can be determined 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.
