Replacing the Lithium Batteries
Overview
There are two lithium batteries ( Figure 201), with a life of approximately 5 years, in
the touch panel that protect stored commands during a power outage. The batteries
are not used when DC power is supplied to the touch panel. You should write down
the replacement date on a sticker or label by adding 5 years to the date of
installation, and then attach it to the back of the touch panel.

Socket
Contact your AMX dealer before you replace the lithium batteries and verify that
they have a current copy of the pages stored in the touch panel. This will avoid any
inadvertent loss of data or a service outage. To replace the lithium batteries, you will
need a Phillips screwdriver and a non-conducting flat-blade tool to slip under each
battery to pry it up and out of the socket.
AXT-CP
Remove the lithium batteries from the AXT-CP:
1.
Discharge the static electricity from your body by touching a grounded object.
2.
Remove the two-pin power connector from the rear side of the touch panel. If
you are using power from AXlink, remove the AXlink connector.
