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.
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.
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.

metal object.
