Table 4 Recommended separation distances between portable and mobile RF
communications equipment and the S/5™ CM (1
Recommended separation distances between portable and mobile RF communications
equipment and the S/5™ CM (1 .
The S/5™ CM (1 is intended for use in an electromagnetic environment in which radiated RF disturbances are
controlled. The customer or the user of the S/5™ CM (1 can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF communications equipment (transmitters)
and the S/5™ CM (1 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.
