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 I 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
people.
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) and as
recommended below, according to the maximum output power of the communications equipment.
