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 the standard device
« Sopix² dental digital x-ray system» exceeds the compliance levels above applicable, the good operation
of the standard device « Sopix² dental digital x-ray system» 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 and
The standard device « Sopix² dental digital x-ray system » is intended to be used in an electromagnetic
environment in which the irradiated RF disturbances are checked. The user of the standard device « Sopix²
dental digital x-ray system » can help to avoid electromagnetic interference by maintaining a minimal distance
between the portable and mobile RF communication devices (transmitters) and the recommended device «
Sopix² dental digital x-ray system» 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.
