If you have a cable TV receiver, satellite receiver, or other 
set-top box that controls your TV signal, connect the 
Infrared Transmitter sensor:

Route the Infrared Transmitter cable from the back of 
the HP Digital Entertainment Center to the cable TV, 
digital cable, or satellite receiver set-top box.

Locate the IR remote receiver area on the front of the 
set-top box. This is where you aim the set-top box 
remote control to change channels, change the 
sound level, and so on.

■

The IR remote receiver area may be behind an 
obvious window on the set-top box.

■

Use the set-top box remote control to locate its IR 
remote receiver area: Hold the remote control 
very close (within 1 inch/2.54 centimeters) and 
press a remote button to change the channel or 
power off the box. As you push a button, 
gradually move the remote control across the 
front of the box until the box responds.

■

Hold a flashlight close to the front of the set-top 
box, and look for a transparent window with a 
small box inside. Test the area by holding the box 
remote close to the window and pushing a button 
until the box responds.

Use a piece of tape to temporarily hold the Infrared 
Transmitter cable tip over the set-top box IR remote 
receiver area while you test the function.

Plug the Infrared Transmitter cable into the Infrared 
Transmitter connector on the back of the HP Digital 
Entertainment Center. 

Test the operation by pointing the HP Digital 
Entertainment Center remote control at the HP Digital 
Entertainment Center IR receiver and pressing a 
channel button. (Be sure you use the HP Digital 
Entertainment Center remote and point it at the 
HP Digital Entertainment Center.)

For permanent attachment, remove the paper from 
the Infrared Transmitter cable tip, and press the tip 
onto the IR remote receiver area on the set-top box.

Repeat these steps for the second set-top box.
