3. Remote control A/V sources with IR Extender  • 
Position the A/V cable’s IR transmission head aiming at the IR Extender of equipment you want to control (A/ V source: DVD, 
VCD, STB etc.)   
• 
At the side of Receiver, you only need to handle the remote controller ( A/ V signal source: DVD, VCD, STB etc.) aiming at the IR 
Extender window of the Receiver, and then you can remotely control your A/V sources. 
 
• 
Note: The IR Extender operation works only with IR remote controls that operate on the 433MHz frequency.    IR remotes 
that operate on other frequencies can not be remotely controlled by the ProA/V Media Extender.    If you cannot remotely 
control your A/V source device through the ProA/V Media Extender, your remote doesn’t operate on the 433MHz frequency.
