Setting Up-Remote Control Feature
This product gives you the ability to control audio/video components using your existing remote
control device. The infrared (IR) signal emitted by your remote control is converted to a radio frequency
(RF) signal at the receiver. It is then sent to the transmitter, where the RF signal is converted back to
the original IR signal and used to control the audio/video source through the IR extender mouse.
To use the IR extender mouse, follow the steps below.
Plug the IR extender mouse into the jack located on the side of the transmitter.
Point the IR extender mouse to the IR sensor on the audio/vido source component.
Position the receiver so that your remote control signal can strike the IR window on the front of
the unit.
To use your remote control, point it at the front of the receiver and operate it as you normally
would.

The Wireless Audio/Video Sender can be used to send a picture from camcorders to any TV without
wires.
•Connect one set of audio/video cables to the audio/video jacks of the transmitter and to the output
jacks of the camcorder, matching the plug colors with the jacks on both the transmitter and
camcorder.
•If your camcorder only has a mini-plug audio/video output, you will need a "Y" adapter patch cord
(which comes with the camera) to convert the mini-plug to RCA plugs.

The Wireless Audio/Video Sender can send computer images and sounds (e.g. high-resolution DVD) to
a large TV screen without running wires between the two. To use this features your computer must be
provided with audio output (sound card or onboard audio) and TV output (VGA card with TV-out,
external VGA-to-TV converter, or onboard TV-out).
•Connect the yellow video plug of the audio/video cable to the video jack on the back of the
computer or external VGA-to-TV converter, and to the video jack of the transmitter.
•Connect the mini stereo plug of the adapter (available in any electronic store) into the AUDIO
OUT jack on back of computer, and the red and white audio/vdieo plugs into the AUDIO LEFT

Placing:Placing:
Placing:Placing:
Placing:
Place the transmitter and receiver on a flat, stable surface to prevent damage from falling.
For optimal performance, try to place the units as high as possible to avoid any possible interference
from people walking between the transmitter and the receiver.
Microwave ovens can cause interference. Be sure you do not position the transmitter and receiver
with a microwave in the path between them.
Adjusting the Audio/Video AntennasAdjusting the Audio/Video Antennas
Adjusting the Audio/Video AntennasAdjusting the Audio/Video Antennas
Adjusting the Audio/Video Antennas
For optimal reception, the antennas on both transmitter and
receiver should be oriented. In most situations the curved face
of the audio/video antennas on both the transmitter and receiver
should be facing each other. If the transmitter and
receiver are less than 10 feet (3 meters) apart, keep the audio/video
antennas flat in their casings.
The audio/video antennas have been designed to pivot but have limited rotation in
either clockwise or counterclockwise directions. Antenna does not rotate freely 360
degrees. Rotating past the point where resistance is felt will result in permanent
damage to both antenna and mechanical stopper.

Auto-Sequence Function for Multiple Location Monitoring
The receiver's built in auto-sequence function is ideal for security use. The receiver can be used with up
to four cameras on four different channels and display them in sequence on a single TV/monitor. The
receiver's various operating modes are set via dipswitches as shown in the following diagram:
Dipswitches 1 ~ 4: Set up the automatic channel sequence function
Slide the channel dipswitch that you wish to view to the ON position.
Diswitch 5: Sets the sequence change interval time
ON: Changes channel every eight seconds.
OFF: Changes channel every four seconds.

Auto-Sequence Function for Multiple Location MonitoringAuto-Sequence Function for Multiple Location Monitoring
Auto-Sequence Function for Multiple Location Monitoring
Note 1: The receiver will auto detect the receiving channels, and display them in sequence. When
only one channel dip switch is in the ON position, the receiver will receive the channel
continuously, without regard to the position of the 5th dip switch. If more than one dip
switch remains on, the auto-sequence function will continue on those channels.
Note 2: When none of the dip switches are in the ON position, the receiver will automatically set the
receiving channel to Channel 1.
Example:
Using the auto-sequence function:
If you have two wireless camera and their channels are set on
CHANNEL 1 and CHANNEL 3, and you wish to monitor the
two channels in sequence, you must slide up the first and third
dip switches to the ON position (see the diagram on the right).
If you wish these two channels to be alternated at eight-second
intervals, slide the DIP 5 switch to the ON position. Leave it in
the lower position for four-second channel change intervals.

Stopping the auto-sequence function:
To stop the auto-sequence function and lock on one channel, leave the dip switch for the channel you
want to receive in the ON position. Slide the others to the lower position.
