The [EQUIPMENT or SYSTEM] is intended for use in an electromagnetic environment in which
radiated RF disturbances are controlled. The customer or the user of the [EQUIPMENT or
SYSTEM] can help prevent electromagnetic interference by maintaining a minimum distance
between portable and mobile RF communications equipment (transmitters) and the [EQUIPMENT
or SYSTEM] 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.
