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. IR signal attenuation POT front FIG. 9 IR signal attenuation POT location 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. 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. AXB-TC and AXB-TCR Television Controllers (& Receivers) Installation and Wiring 4. Turn the POT screw clockwise one-eighth turn to increase signal saturation. Then, send an IR control signal to the television. If the television performs correctly, go to step 5. If not, repeat this step until the television performs the correct operation. 5. Send an IR control signal to the television for all programmed operations. If an operation fails, go back to step 4. 6. Reattach the enclosure and refasten the two screws. Replacing the Lithium Battery There is a lithium battery (FIG. 10), with a life of approximately five years, in the television controller that protects stored presets if there is a power loss. The battery is not used when DC power is supplied to the television controller. You should write down the replacement date on a sticker or label by adding 5 years to the date of installation, and attach it to the bottom of the television controller. Battery (CR2025 type) socket FIG. 10 Lithium battery and socket All control commands in television controller memory are lost when the lithium battery is replaced. Contact your AMX dealer before you replace the lithium battery to verify that they have a current copy of the IRLIB program file for your television controller. This will prevent any inadvertent loss of data or service outage. Static electricity can damage electronic circuitry. Before removing the battery from the enclosure, discharge any static electricity from your body by touching a grounded metal object. Use a flat-blade tool (non-conducting) that can be slipped under the lithium battery to pry it up and out of the socket. 1. Discharge the static electricity from your body. 2. Unplug all cables from the television controller. 3. Remove the two Phillips-head screws on the bottom of the television controller enclosure. 4. Pull the two enclosure halves apart and set the bottom portion of the enclosure on a flat surface. 5. Locate the battery on the circuit card. 6. Carefully pry the battery out of its socket and insert the new battery. Write down the next replacement date on a label by adding 5 years to the replacement date; attach it to the bottom of the television controller. 7. Reattach the enclosure and refasten the two screws. 8. Plug all cables back into the television controllers. AXB-TC and AXB-TCR Television Controllers (& Receivers) Installation and Wiring There is a danger of explosion if you replace the battery incorrectly. Replace the battery with the same or equivalent type, recommended by the manufacturer. Dispose of the used battery according to the manufacturer's instructions. Never recharge, disassemble, or heat the battery above 212 °F (100 °C). Never solder directly to the battery or expose the contents of the battery to water. AXB-TC and AXB-TCR Television Controllers (& Receivers) Installation and Wiring AXB-TC and AXB-TCR Television Controllers (& Receivers) Programming Information Programming Information Overview The television controllers are controlled with channel settings, IR functions, and Axcess Send_Commands. You create software programs with the AMX Axcess programming software. Use the programming information in this section with the Axcess Programming Guide to program television controllers. After you create the IRLIB program, download it to the non-volatile (battery protected) memory in the television controller. Refer to the IRLIB Infrared Library Management Program ins...
