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.

1.Connect the plug end of the supplied IR emitter cable to the IR—NetCommand Output jack on the TV main 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 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.

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.

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.
