a. The Model 3120 PRM is intended for use in an electromagnetic environment in which
radiated RF disturbances are controlled. The customer or the user of the Model 3120 PRM
can help prevent electromagnetic interference by maintaining a minimum distance between
portable and mobile RF communications equipment (transmitters) and the Model 3120 PRM
as recommended above, according to the maximum output power of the communications
equipment.
can help prevent electromagnetic interference by maintaining a minimum distance between
portable and mobile RF communications equipment (transmitters) and the Model 3120 PRM
as recommended above, according to the maximum output power of the communications
equipment.
b. 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.
