IR Emitter NetCommand® and TV Guide On Screen

5.Place any unused ends behind the devices to prevent stray signals from reaching the IR sensors.

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.

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.
