Interacoustics Aqua Stim Instructions For Use Manual page 25

Guidance and manufacturer's declaration — electromagnetic immunity
The AquaStim is intended for use in the electromagnetic environment specified below. The customer or
the user of the AquaStim should assure that it is used in such an environment,
Immunity test
Conducted RF
IEC / EN 61000-4-6
Radiated RF
IEC / EN 61000-4-3
NOTE1 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 AquaStim is used exceeds the applicable RF compliance level above, the AquaStim should be
observed to verify normal operation, If abnormal performance is observed, additional measures may be
necessary, such as reorienting or relocating the AquaStim.
b) Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

should be used no closer to any
parts of the AquaStim, including
cables, than the recommended
separation distance calculated
from 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 and d is
the recommended separation
distance in meters (m).
Field strengths from fixed RF
transmitters, as determined by an
electromagnetic site survey,
should be less than the
compliance level in each
frequency range.
