C. Introduction
Thank you for purchasing this 2.4GHz Digital AV Sender. This sender system is a digital
wireless audio/video sender that uses 2.4GHz Frequency Hopping technology and GFSK
modulation, and random ID codes to protect personal privacy.
There are over billion hopping sequences to minimize interference and deliver consistently
an excellent video and audio quality up to 150 meters away.
This sender system also integrates an IR remote control extender to allow you to control the
audio or video source from another room using your existing remote controller.
Using this 2.4GHz Digital Wireless A/V Sender, 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 DVD, 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.
Safety & Security Application:
• Connect a camera 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 the meeting from another room.
• Extend the DVR control wirelessly, connect the main out(CVBS) to the transmitter,
and receiver to the TV monitor, the guard people can look at the DVR screen in the
TV monitor far from DVR, and control the DVR by its remote control far way
• And many more uses!

G. 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 the receiver and sends it back to the transmitter where the RF signal is converted
back to the original IR signal and control the audio/video source such as DVD ,DVR, VCR ,
etc.
In order to obtain optimum performance of the remote control extender, please operate as follow:
The first you need to plug the IR extender provided in the IR extender port of the transmitter
and put the IR eye close to IR receiving window of A/V source, and then aim the existing
remote control at the IR window of the receiver within 5 meter.
Following is the example for DVD Player installation:
1. Transmitter(TX) uses orange color jack IR extender cable, and Receiver(RX) uses black
color jack IR extender cable as below:
2. Install IR Cable
2.1. Transmitter’s IR to the IR of DVD Player:
2.2. Take off the sticker of IR terminal and cover on DVD IR hole:
Caution: only the 1/3 top of terminal is available, so must let
the 1/3 top accurately to cover IR hole of DVD.
2.3. Stick the terminal of receiver IR to anywhere of Monitor.
Only available
on this side.
Caution: Only the 1/3 top of receiver terminal is available, so
DVD remote control must accurately aim at the available
part.
H. Pairing the transmitter and receiver
Before shipment of these products, they have been matching by ID code, you can
immediately instantly use. If wants to re-pair them, you have to follow the instructions as
below:
1. Power on the transmitter and receiver by inserting the power adaptor jack.
2. Press the pair button of transmitter or receiver and not release until the power LED begin
to flash, then release the pair button.
3. They will enter into the pairing state and automatically link to each other by ID code after
step 2 finished.
4. Please don’t turn off their power switch during the paring status.
5. When pairing successfully, the power LED for both will be lit directly (not flash)
Pairing Button
Please note:
Pressing the pairing buttons for transmitter and receiver is not necessary at the same time,
and they are not necessarily put near or side by side in pairing status, around within 3 meters
far is OK
Under the transmission, you can see the strength on the monitor as below:
I. Use Notics
1.
2.
Be sure the transmitter and the receiver were connected to the equipment correctly (e.g.
Connect the transmitter to the camera, and the receiver to the TV or DVR).
When DC plug is pulled out from transmitter or receiver, it needs to wait for a few
seconds to insert it again.
3.
Adjust antenna to decrease interference. (vertical or horizontal)
4.
In most situations, one pair has a better distance up to 150 meter(open site). When two pairs or more
are used at the same time, It can automatically jump to different channels. But the distance between
transmitter and transmitter (receiver and receiver), preferably greater than 2 meters far.
5.
If there are some reasons cause the devise stop, you can try to turn off the power then on again and
make the devise re-link(re-pairing)
6.
It is suggested to have 10 pairs mostly operated in same location, but the pairing can not be at the
same time.
J. Troubleshooting
Problems
Possible Solution
Check all cable connections
Make sure power plugs are pushed all the way in
No picture or sound
Check power switches on the remote TV or DVR and Video
source(Camera, Camcorder, etc.)
Check if the POWER LED of the transmitter and receiver is lighting or
not? Their LINK LED should be lit.
If Their LINK LED should not be lit, you must re-pair their codes
following the D. instruction of the manual
Adjust receiver and transmitter antenna orientation
Interference: picture or
audio
Try to place transmitter and receiver in a more close-in location
If using a microwave oven, turn it off.
Remove microwave oven or wireless router from path between
transmitter and receiver
