Recommended separation distances for portable and mobile RF communication equipment and the EUT
The EUT is intended for use in the electromagnetic environment in which radiated RF disturbances are controlled. The customer or user of the EUT can help
prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communication equipment (transmitters) and the
EUT 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 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 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.
