Recommended Separation Distance Between
Portable and Mobile RF Communications Equipment and the Model @ 3 Vrms
e model VisiClear™ is intended for use in the electromagnetic environment in which radiated RF
disturbances are controlled. e customer or the user of the model VisiClear™ can help prevent electromagnetic
interference by maintaining a minimum distance between portable and mobile RF communications equipment
(transmitters) and the model VisiClear™ 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 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.
NOTE 2: ese guidelines may not apply in all situations. Electromagnetic propagation is aected by absorption
and reection from structure, objects, and people.
