Recommended Separation Distances Between Portable and Mobile RF Communications
Equipment and the SONIX
The SONIX is intended for use in an electromagnetic environment in which radiated RF disturbances
are controlled. The customer or the user of the SONIX can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF communications equipment
(transmitters) and the SONIX, 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 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: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption
and reflection from structures, objects and people.
