Recommended separation distances between
portable and mobile RF communications equipment and the Model CP30DW
The Model CP30DW is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The customer or the user of the Model CP30DW can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the Model CP30DW 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.
NOTE1. At 80 MHz and 800 MHz, the separation distance for higher frequency range applies.
NOTE2. These guidelines may not apply in all situations. Electromagnetic propagation is affected
by absorption and reflection from structures, objects and people.
