EMC
Guidance and manufacturer’s declaration — electromagnetic immunity
The Sonicator 718 and Sonicator 719 are intended for use in the electromagnetic environment
specified below. The customer or the user of this unit should assure that it is used in such an
environment.
NOTE 1 At 80 MHz and 800 MHz, 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.
a
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and
land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted
theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an
electromagnetic site survey should be considered. If the measured field strength in the location in which
the Sonicator 718 / Sonicator 719 should be observed to verify normal operation. If abnormal performance
is observed, additional measures may be necessary, such as reorienting or relocating the Sonicator 718 /
Sonicator 719.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

of the transmitter in watts (W) according to
the transmitter manufacturer and d is the
recommended separation distance in metres
