Recommended separation distances between portable and mobile RF communications
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 (transmittters) and the 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 metres
(m) can be determined 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 80MHz 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.
