Replacing the Lithium Batteries

Overview

There are two lithium batteries ( Figure 169) on the mini-touch panel circuit card,
with a life of approximately 5 years. They protect stored commands and pages
against power loss. The batteries are not used when DC power is supplied to the
mini-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 mini-touch
panel for future reference.
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.
