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. 
THE AUDIO/VIDEO QUALITY ADJUST
Sender broadcast their high-quality audio and video using hidden omni-
directional antennas, only need to put the transmitter and receiver vertically and 
make some adjustments, until picture and sound quality became perfect. 
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 2280T, 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 the
A/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 
13 
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.
