Table 4 – Minimum Safe Distance
WARNING:
An Antenna extender cable is shipped with the TX5XX, it is meant to
hold the antenna at the minimum safe distance from the human body.
This extender cable MUST be used whenever the Transmitter is
operated in a mobile environment (such as on a camera) and the
user should mount the transmitter in a way that does not defeat the
purpose of this cable. If the transmitter is mounted in a manner other
than intended with the extender cable, it SHALL be the user’s
responsibility to ensure the above minimum distance from ‘any’
human being. Avalon RF will help/advise you if necessary.
If the antenna you received is not one of the above, use the next
higher distance or call/e-mail Avalon RF.
Operating range will depend on the transmit and receive antennas
used - a wide choice of antennas is available from Avalon RF. Please
visit the website (
www.avalonrf.com
) for more details.
For fixed installations, power saving can be achieved by turning off
the video camera or the video source. A ‘video presence’ detection
circuitry will turn off the power amp when no video is detected - power
will be restored when the video signal is restored. Besides power
conservation, it also eliminates high power RF transmission by
reducing the output by about 30 dB (1000 times less) when no video
is present.
