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.

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.
