Replacing the Battery
There is one lithium battery on the touch panel card, with a life of approximately 2.5 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.
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.
