Acteon SOPRO 617 Betriebsanleitung Seite 11

a The fixed transmitter field levels, such as the base stations of the radio telephones (cellular/wireless) and
the terrestrial mobile radios, amateur radio, AM, FM, and TV radio communication cannot be theoretically
assessed precisely. To obtain the electromagnetic environment due to the fixed RF transmitters, a site
measurement should be performed. If a field level measured in the use environment of SOPRO device
exceeds the compliance levels above applicable, the good operation of SOPRO device should be checked.
If abnormal operations are proved, some further measures should be taken, such as reorientation or
relocation of the standard device.
b Above the 150 kHz to 80 MHz frequency band, the field level should be lower than 3 V/m.
Recommended separation distances between the portable and mobile RF communication devices
SOPRO device is intended to be used in an electromagnetic environment in which the irradiated RF
disturbances are checked. The user of SOPRO device can help to avoid electromagnetic interference by
maintaining a minimal distance between the portable and mobile RF communication devices (transmitters)
and the recommended SOPRO device such as recommended below, depending on the maximal output power
of the communication device.

For the transmitters whose maximal output is not listed above, the recommended separation distance d in
metres (m) can be determined by using the equation applicable to the transmitter frequency, where P is the
maximal output of the transmitter in watts (W) rated by the transmitter manufacturer.
Note 1: At 80 MHz and at 800 MHz, the separation distance given in the higher frequency band applies.
Note 2: These recommendations may not apply in every situation. The electromagnetic wave propagation is
modified by absorption and reflection due to the structures, objects and persons.
