disturbances are controlled. The 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 are 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 metres (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, 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 800MHz, 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.
