This device is intended for use in an electromagnetic environment in which radiated RF disturbances are
controlled. Electromagnetic interference may be prevented by maintaining a minimum distance between
portable and mobile RF communications equipment (transmitters) and this device as recommended in the
table 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 affected
by absorption and reflection from structures, objects, and people.
