Notes on Use
㸦㸯㸧
The service frequencies and transmit power outputs of CW-5HD vary depending on the
designated regions, because each region has different local regulations or restrictions on
radio waves. The units are programmed in the
factory prior to shipping. Therefore, a CW-5HD
shipped to one region can not be used in a
different region.
㸦㸰㸧
Outdoor usage of the 5GHz frequency band,
which the CW-5HD uses, is controlled by
region. This table shows the approved
frequencies and the corresponding channels of CW-5HD in US region.
㸦㸱㸧
The maximum transmission distance varies depending on the surroundings, radio wave
conditions, buildings structural composition etc. Although the indoor transmission
distance is indicated as 30m (POWER MODE=HIGH), however this is not a guaranteed
operational level
㸦㸲㸧
When the CW-5HD TX and RX are located close to each other, the received signal may be
too strong and may disturb the video. When the CW-5HD TX and RX are used close to
each other (say 3m or less as an example), set the POWER MODE switch of CW-5HD TX
in LOW mode.
㸦㸳㸧
CW-5HD can not be equipped with external antennas.
㸦㸴㸧
The SDI output of CW-5HD conforms to SMPTE-292M/SMPTE-259M. However, in some
linked conditions, clock jitter of SDI signals may exceed the regulated values.
㸦㸵㸧
CW-5HD uses SDI embedded audio, however only Audio channels 1 and 2 can be
transmitted.
㸦㸶㸧
It should be understood that the quality level of video transmitted by wireless signal is not
as
good as that by hard-wired cable signals.
㸦㸷㸧
CW-5HD TX (transmitter) should be installed on the V-Mount interface of a video camera.
Depending on connectivity, installing CW-5HD TX with equipment other than a video
camera may cause problems to CW-5HD TX or other equipment
