Recommended Separation Distances Between Portable and Mobile RF Communications Equipment and
This Device
This device is intended for use in electromagnetic environments in which radiated RF disturbances are
controlled. The user of this device can help prevent electromagnetic interference by maintaining a minimum
distance between portable and mobile RF communications equipment (transmitters) and this device as out-
lined below, according to the maximum output power of the communications equipment.

For transmitters with maximum output power not stated above, the recommended separation distance
(d) in meters can be estimated using the formula applicable to the transmitter frequency, where P is the
maximum output power rating of the transmitter in watts (W) provided by the transmitter manufacturer.
NOTE 1: At 80 MHz and 800MHz, the separation distance for the higher frequency range applies.
NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation is a ected by ab-
sorption and refl ection from buildings, objects and people.
