Recommended separation distances between portable and mobile RF communication
The device is intended for use in an electromagnetic environment where radiated RF disturbancesare under control.
User can help prevent electromagnetic interference by keeping the device at a minimum distance from portable and
mobile RF communications equipment (transmitters). Below table details the maximum output power of transmitter:

For transmitters rated at a maximum output power not listed above, the recommended separation distance d in met-
res (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.
