The 85101/85102 is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the
user of the 85101/85102 can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the 85101/85102 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 meter's (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.
