Owandy-Cam HD • User’s manual 11
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.

1 0.16 1.16 2.33
10 3.66 3.66 7.36
100 11.6 11.6 23.3
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.
