AXB-TC and AXB-TCR Television Controllers
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. 11), 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.

Static electricity can damage electronic circuitry. Discharge any static electricity from
your body by touching a grounded metal object before adjusting the POT.
