portable and mobile RF communications equipment and the EPK-i
The EPK-i is intended for use in the electromagnetic environment in which radiated RF disturbances are controlled. The
customer or the user of the EPK-i can help prevent electromagnetic interference by mainteining a minimum distance between
portable and mobile RF communications equipment (transmitters) and the EPK-i 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 quidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and
reflection from structures, objects and people.
