a
The field strengths of fixed transmitters e.g. base stations of mobile telephones and mobile radio devices, amateur radio,
AM and FM radio broadcasting, and TV broadcasting cannot be accurately predicted. In order to assess the electromagnetic
environment with regard to fixed RF transmitters, a study of the electromagnetic phenomena at the location should be
considered. If the measured field strength in the location in which the Soleo Sono device is used exceeds the above
compliance level, the Soleo Sono device must be monitored to verify normal operation. If abnormal performance is observed,
additional measures may be necessary, such as the realignment or relocation of the Soleo Sono device.
b
In the frequency range of 150 kHz to 80 MHz, the field strengths should be less than 3 V/m.
Recommended separation distances between portable and mobile RF communications equipment and the Soleo
Sono device
The Soleo Sono device is intended for use in an electromagnetic environment in which RF disturbances are controlled. The
customer or the user of the Soleo Sono device can thus help to prevent electromagnetic interference by maintaining a
minimum distance between portable and mobile RF communications equipment (transmitters) and the Soleo Sono device –
depending on the output power of the communications equipment as indicated below.

For transmitters for which the maximum nominal output is not specified in the above table, the recommended separation
distance d in metres (m) can be determined using the equation given for the corresponding column, where P is the maximum
rated power of the transmitter in watts (W) in accordance with the manufacturer of the transmitter.
NOTE 1: At 80 and 800 MHz, the higher frequency range applies.
NOTE 2 These guidelines may not apply in all cases. Electromagnetic propagation is affected by absorption and reflection
from structures, objects and people.
