IR (Infrared) Control
Finding the IR sensor. To correctly position the IR Control cable, you need to find your
cable box or satellite box’s IR sensor (the connection is fully described in the examples in
Chapters 2 and 3). To locate the IR sensor, look for a tiny round bulb behind the dark,
translucent plastic “window”—the IR window—on the front of your cable or satellite box.
A flashlight might help you see it. Position the IR emitters so they are centered on the IR
sensor and stick out about 1.5 inches.
Choosing an IR code in Guided Setup. After setting up your Recorder, you’ll complete
Guided Setup (see the User’s Guide for more information). During Guided Setup, you’ll
be asked to test and select an IR code. Each IR code signals a particular cable or satellite
box model to change channels. If none of the codes changes the channel on your particular
cable or satellite box, see page 44 for troubleshooting tips. If you find a code or codes that
work, but none of the codes is reliable or consistent, try optimizing the IR Control
connection (see below).
Optimizing the IR Control connection. The IR Control cable works better if its emitters
and the IR window on the cable or satellite box are shaded from other infrared signals.
You can create an IR cover to decrease the interference from other signals. This solution
may help if changing channels with an IR Control cable is unreliable or inconsistent, but
not if channels don’t change at all.
Test whether an IR cover might be effective simply by draping a magazine, a towel, or a
dark cloth over the front of cable or satellite box, including the IR emitters. (See the
diagram on page 11.) Do not block the Recorder’s IR window. Try changing channels
several times with the remote control. If channels change more reliably this way, you may
want to make an IR cover.
IR Control cable
The small “bulbs” on the IR
emitters do not visibly light up
when they send an IR signal. If you find
that channels are not changing, see
page 44 for troubleshooting help. If
channels change unreliably or
inconsistently, try the tips on optimizing
the IR Control connection (to the right).
