Recommended separation distances between portable and mobile RF communications
equipment and the device
The device is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The customer or user of the device can help prevent
electromagnetic interference by maintaining a minimum distance between portable and
mobile RF communications equipment (transmitters)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 in meters (m), scan 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.
NOTE1 : At 80MHz 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.
