UUUsssiiinnnggg ttthhheee RRReeemmmooottteee CCCooonnntttrrrooolll FFFeeeaaatttuuurrreee 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: 2.3. Stick the terminal of receiver IR to anywhere of Monitor. Caution: only the 1/3 top of terminal is available, so must let the 1/3 top accurately to cover IR hole of DVD. Caution: Only the 1/3 top of receiver terminal is available, so DVD remote control must accurately aim at the available part. Only available on this side.

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.
