Installation and Wiring

XB-TC and AXB-TCR Television Controllers (& Receivers)

Television Power Sensor Adjustment

After connecting the CC-IR to the television, the power sensing POT, on the rear of the television

controller (see FIG. 1 on page 1), may require adjustment to detect the television's power status:

Use a Phillips-head screwdriver and flat-blade tool (non-conducting) to adjust the POT screw.

1. Turn the television off.

2. Locate the POT screw on the circuit card and turn it clockwise 20 full turns or until it clicks. The red

TV Sensor indicator, located on the front panel, should be dark.

3. Turn the television on.

4. Turn the POT screw counterclockwise until the TV Sensor indicator lights. Then, turn the POT

screw counterclockwise one full turn.

5. Turn television power off. If the TV Sensor indicator is lit, turn the POT screw clockwise until the

indicator goes dark.

6. Reattach the enclosure and refasten the two screws.

IR Signal Attenuation Adjustment

If you experience television control problems after connecting a CC-IRC IR Emitter to the television, the

television may be too sensitive to interpret the IR signals generated by the television controller. You can

use the IR signal attenuation POT, located inside the television controller (FIG. 9), to decrease the

strength of the IR signal.

Refer to Internal Jumper Settings section on page 5 to put the AXB-TC or AXB-TCR in IR attenuation

mode.

Use a Phillips-head screwdriver and flat-blade tool (non-conducting) to adjust the POT screw.

1. Remove the two Phillips-head screws on the bottom of the television controller enclosure.

2. Pull the two enclosure halves apart and set the bottom portion of the enclosure on a flat surface.

3. Locate the POT screw on the circuit card and turn it counterclockwise with a flat-blade tool until it

stops.

Static electricity can damage electronic circuitry. Discharge any static electricity from

your body by touching a grounded metal object before adjusting the POT.
