Chapter 2. TV Connections 31
IR Emitter NetCommand® and TV
Guide On Screen
An IR emitter cable is included with the TV.
The NetCommand system uses emitters connected to
the
IR EMITTER
jack to control other devices such
as VCRs, DVD players, cable boxes, and satellite receiv-
ers. This control system is shared with the TV Guide On
Screen system.
1. Connect the plug end of the supplied IR emitter cable
to the
IR EMITTER NetCommand®
jack on the
TV back panel.
2. Run the cable for each of the emitter ends under,
alongside, or over each device to be controlled so
that the emitter end is in front of the area where the
remote control sensor is located.
3. Position the emitter end with the emitter bulb facing
the remote control sensor. The bulb emits infrared
light in a cone-shaped pattern. Place the bulb far
enough from the sensor to allow the cone pattern to
reach the sensor.
The IR sensor is usually behind the plastic window
of the front display panel. It is sometimes visible
with the aid of a flashlight and is normally a round or
square cutout behind the plastic. If you cannot see
the sensor and the device’s Owner’s Guide does not
specify the location, you can find it by following these
steps using the device’s remote control:
a. Hold the remote about one-half inch from the
front of the device. Starting from one end of the
display window plastic, press the
POWER
button.
b. If the device does not respond, move the remote
control one inch toward the center and try again.
c. Repeat this until the device responds.
d. Note this location and then start over from the
other end of the display window plastic, repeating
until the device responds again.
The remote control sensor is somewhere between
these two positions. This is usually enough accu-
racy for placement of the IR emitters.
With some devices, the emitter works better
facing downward from the top of the device.
Experiment if needed.
4. Secure the emitter ends in place using double-sided
tape.
5. Place any unused ends behind the devices to prevent
stray signals from reaching the IR sensors.

IR sensor on each device.
IMPORTANT
Position IR emitters so that each device’s
sensor “sees” the signal from only one
emitter. Otherwise, a device receiving signals
from multiple sources (remote controls, IR
emitters) may not respond at all.
