For transmitters rated at a maximum output power not listed above, the recommended separation
distance d in metres (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.
The Sonicator 718 and Sonicator 719 are intended for use in an electromagnetic environment in
which radiated RF disturbances are controlled. The customer or the user of the Sonicator 718 /
Sonicator 719 can help prevent electromagnetic interference by maintaining a minimum distance
between portable and mobile RF communications equipment (transmitters) and the Sonicator
718 / Sonicator 719 as recommended below, according to the maximum output power of the
communications equipment.
