Recommended separation distances between portable and mobile communication equipment and this
This equipment is intended for use in an electromagnetic environment in which radiated RF disturbances are
controlled. The customer or the user of this equipment can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF communication equipment (transmitters)
and this equipment as recommended below, according to the maximum output power of the communications
equipment.

For transmitter 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 of the transmitter in watts (W) according to the transmitter manufacturer.
Note 1. At 80MHz and 800MHz 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.
