a The fixed transmitter field 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 electroma-
gnetic environment due to the fixed RF transmitters, a site measurement should be performed. If a field level measured in the use
environment of Owandy-Cam HD device exceeds the compliance levels above applicable, the good operation of Owandy-Cam HD
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
and Owandy-Cam HD device
Owandy-Cam HD device is intended to be used in an electromagnetic environment in which the irradiated RF disturbances are
checked. The user of Owandy-Cam HD device can help to avoid electromagnetic interference by maintaining a minimal distance
between the portable and mobile RF communication devices (transmitters) and the recommended Owandy-Cam HD 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 modified by absorption and reflection due
to the structures, objects and persons.
