a The fi xed transmitter fi eld levels, such as the base stations of the radio telephones (cellular/wireless) and the terrestrial
mobile radios, domestic radio, AM, FM, and TV radio communication cannot be theoretically assessed precisely. To obtain the
electromagnetic environment due to the fi xed RF transmitters, a site measurement should be performed. If a fi eld 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 fi eld level should be lower than 3 V/m.
Recommended separation distances between the portable and mobile RF communication devices
SOPROCARE 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 maximum 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 modifi ed by absorption
and refl ection due to the structures, objects and persons.
