Replacing The Battery; Axt-Cp4/A Battery Replacement - AMX COLOR TOUCH PANELS WITH AUDIO (G3 FIRMWARE) Instruction Manual

Replacing the Battery

There is one lithium battery on the touch panel card, with a life of approximately 5 years. It protects
stored commands and pages against a power outage. The battery is not used when DC power is
supplied to the touch panel. Write down the replacement date on a label by adding 2.5 years to the
date of installation; attach it to the panel for future reference.
FIG. 41 Lithium battery and socket
Static electricity can damage electronic circuitry. Before removing the touch panel
circuit card from any enclosure, discharge any accumulated static electricity from
your body and flat-blade tool by touching a grounded metal object.
Before replacing the lithium battery, make sure you have a current copy of the pages stored in the
touch panel. This will avoid any inadvertent loss of data or service outage. To replace the lithium
battery, you will need a Phillips screwdriver and a non-conducting flat-blade tool to slip under the
battery to pry it up and out of the socket.
