B. Introduction to 5.8GHz Wireless A/V Link
This sender system is a wireless audio/video sender that uses
advanced wireless communication technology to deliver consistently
sharp audio and video up to 100 meters away. By transmitting at a
very high frequency (5.8 GHz), it avoids the crowded 900 MHz band
used by many cordless telephones and other wireless audio/video
transmitters. It’s superior quality is due to wide-band FM rather than
AM signal modulation.
It also integrates an UHF remote control extender to allow you to
control the audio or video source from another room using your
existing remote controller.
Using sender system, you can enjoy greater convenience and security
in many ways:
General Application
•Watch the movie you rent on any TV in house without moving
your VCR, laser disc player or running messy cables.
•Watch cable or satellite programs on any TV in house.
•Listen to stereo-quality music from your receiver on any powered
speakers inside or outside the house.
•Uses multi-receivers for broadcasting to numerous TV sets in other
rooms.
•Show computer images on a remote TV. (Additional equipment
required)
Safety & Security Application:
•Applies as a wireless security system.
•Monitor your sleeping baby, playing children, the elderly, or the
disabled on TV using your existing camcorder.
•See who is outside the door on TV through your camera or
miniature CCD camera.
•Monitors and records meeting from another room.
•And many more uses!

E. Orienting Units for Optimum Performance
This sender system should be placed on a flat, stable surface to prevent
damage to it from falling.
For optimum performance, both the audio/video and remote control antennas
should be carefully oriented as described below. In addition, to use the remote
extension feature, the transmitter itself must be specially oriented so it can
relay the converted remote control signal back to the audio/video source (see
following section titled "Using The Remote Control extension Feature"). For
maximum operating range, try to minimize the number of obstacles (e.g. your
TV or other electronics, large furniture) where between the transmitter and
receiver units.
Orienting the Audio/Video Antennas
Sender broadcast their high-quality audio and video using directional
antennas, which must be oriented in certain configurations for best results.
The antennas have been designed to pivot and rotate in-almost any
direction.
In most situations, the outside face of the antennas on both the transmitter
and receiver should be facing one another and perpendicular (at a right
angle) to an imaginary line drawn between the two units. Three examples
are shown Fig-l, Fig-2 and Fig-3. Since all homes are different, for optimum
reception, additional slight pivots or rotations may be necessary. If the
transmitter and receiver are less than 10 feet apart, suggest keeping the
antennas flat in their casings since the distance is so short.
Fig-1: How to orienting the 5.8GHz audio and video antennas.

Fig-2 Fig-3
F. Using the Remote Control Feature
This sender system not only allows you to send crisp audio/video from one
area to another, it also gives you the ability to control the source using your
existing remote control device. It converts the infrared (IR) signal emitted by
your remote control to a radio frequency (RF) signal in UHF band at the
receiver and sends it back to the transmitter where the RF signal is converted
back to the original IR signal and beamed to the audio/video source.
There is one way to get your source A/V equipment to be controlled by using
existing remote control through remote control feature:
There’s a IR output cable wiring of the transmitter；, put the IR end close to
IR receiving part of A/V source.

Sometimes, it may be difficult or even impossible to orient the transmitter unit
such that it can be "seen" (means face-to-face) by theA/V equipment you wish
to control. Perhaps there is no good surface that allows for this or perhaps you
wish to control. Or perhaps you wish to remotely control A/V equipment in
different locations without re-orienting the transmitter. So, in this case, to use
in extender will be more convenient.
In order to obtain optimum performance of the remote control extender,
please operate as follow:
At the transmitter：Put IR Header near opposite to AV source IR receiver,
and keep remote antenna (outlet of A/V cable), in loose state with its end away
from cable.
At the receiver:
Direct remote control straightly against IR receiver in a distance of 5
meter, and keep remote antenna (outlet of A/V cable), in loose state with its
end away from cable.
