Recommended separation distances between portable and mobile RF communications
equipment and this device:
This device is intended for use in an electromagnetic environment in which radiated RF 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 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) 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.
