Recommended Separation Distances between Portable and Mobile RF
Communications Equipment and the P7500 Model
The P7500 is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled.
The customer or the user of the P7500 can help prevent electromagnetic interference by maintaining a minimum dis-
tance between portable and mobile RF communications equipment (transmitters) and the P7500 as recommended
below, according to the maximum output power of the communications equipment.
