Recommended separation distances between portable and mobile RF communications
equipment and the Sonicator 740
The Sonicator 740 is intended for use in an electromagnetic environment in which radiated RF disturbances
are controlled. The customer or the user of the Sonicator 740 can help prevent electromagnetic interference
by maintaining a minimum distance between portable and mobile RF communications equipment
(transmitters) and the Sonicator 740 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 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 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from
structures, objects and people.
