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 the 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 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 propagation is affected by absorption and
reflection from structures, objects and people.
