Recommended separation distances betweenPortable and mobile RF communications equipment and the Model P93DW/P93DE
The Model P93DW/P93DE is intended for use in the electromagnetic environment in which
radiated RF disturbances are controlled. The customer or user of the Model P93DW/P93DE can
help prevent electromagnetic interference by maintaining a minimum distance between portable
and mobile RF communications equipment (transmitters) and the Model P93DW/P93DE as
recommended below, according to the maximum output power of the communications equipment.

For transmitters rated at 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.
