which radiated RF disturbances are controlled. e customer or 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 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) 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 aected by
absorption and reection from structures, objects, and people.
