6. NetCommand IR Control 55
IR Emitter Placement
An IR emitter cable is included with the TV.
The NetCommand system uses emitters connected
to the IR—NetCommand Output jack to control other
devices such as DVD players, cable boxes, satellite
receivers, and VCRs.
Connect the plug end of the supplied IR emitter

cable to the IR—NetCommand Output jack on the
TV main panel.
Run the cable for each of the emitter ends under, 2.
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.
Position the emitter end with the emitter bulb facing
3.
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 device’s 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, repeat-
ing until the device responds again.
The remote control sensor is somewhere
between these two positions. This is usually
enough accuracy for placement of the IR emit-
ters.
In some cases, the emitter works better facing
downward from the top of the device. Experi-
ment to find what works best.
Secure the emitter ends in place using double- 4.
sided tape.
Place any unused ends behind the devices to

prevent stray signals from reaching the IR sensors.

Place IR emitters so the signal can be “seen” by the 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.
