Recommended separation distances between portable and mobile RF
communications equipment and the device.
The device is intended for use in an electromagnetic environment in which
radiated RF disturbances are controlled. The customer or the user of the device
can help prevent electromagnetic interference by maintaining a minimum distance
between portable and mobile RF communications equipment (transmitters)
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) accordable 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 propogation is
affected by absorption and reection from structures, objects and people.
