Manufacture's Declaration
A1.1 Electromagnetic Emissions - for all Equipment and
Systems
Guidance and manufacture's declaration–electromagnetic emission
The SONOTRAX Series Ultrasonic Pocket Doppler is intended for use in the electromagnetic
environment specified below. The customer or the user of the device should assure that it is used in such
an environment.
Emission test Compliance
The SONOTRAX Series Ultrasonic Pocket Doppler uses RF
RF emissions energy only for its internal function. Therefore, its RF emissions
Group 1
CISPR 11 are very low and are not likely to cause any interference in nearby
electronic equipment.
The SONOTRAX Series Ultrasonic Pocket Doppler is suitable
for use in all establishments, including domestic establishments
RF emission
Class B and those directly connected to the public low-voltage power
CISPR 11
supply network that supplies buildings used for domestic
purposes.

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
wood,
the location in which the SONOTRAX Series Ultrasonic Pocket Doppler is used exceeds the
applicable RF compliance level above, the SONOTRAX Series Ultrasonic Pocket Doppler should be
with
observed to verify normal operation. If abnormal performance is observed, additional measures may
be necessary, such as reorienting or relocating the SONOTRAX Series Ultrasonic Pocket Doppler.

Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
