90 HP Digital Entertainment Center
Infrared Transmitter Installation
If you have a cable TV receiver, satellite receiver, or other
set-top-box that controls your TV signal, connect the
Infrared Transmitter Sensor:
1 Route the IR transmitter cable from the back of the
HP Digital Entertainment Center to the cable TV,
digital cable, or satellite receiver set-top-box.
2 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.
3 Use a piece of tape to temporarily hold the IR
transmitter cable tip over the set-top-box IR remote
receiver area while you test the function.
4 Plug the IR transmitter cable into the Infrared
Transmitter connector on the back of the HP Digital
Entertainment Center.
5 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.)
6 For permanent attachment, remove the paper from
the IR transmitter cable tip and press the tip onto the
IR remote receiver area on the set-top-box.
7 Repeat these steps for the second set-top-box.
