Manufacturer's EMC declaration

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 where the device Soleo SonoStim / Soleo Stim is used exceeds
the applicable RF compliance level above, the device Soleo SonoStim / Soleo Stim should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating
the device Soleo SonoStim / Soleo Stim.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
Recommended separation distances between portable and mobile RF telecommunications equipment and the
Soleo SonoStim / Soleo Stim device
The Soleo SonoStim / Soleo Stim device is intended for use in an environment in which radiated RF disturbances are
controlled. The customer or user of the Soleo SonoStim / Soleo Stim device can help prevent electromagnetic interference
by maintaining a minimum distance between portable and mobile RF telecommunications equipment (transmitters) and the
Soleo SonoStim / Soleo Stim device, as recommended below, according to the maximum output power of the
communications equipment.

For transmitters rated at a maximum output power which is not listed above, the recommended separation distance d in
metres (m) can be determined 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.
We reserve the right to make changes.
