10.4" Touch Panels
Replacing the Batteries
There are two lithium batteries on the touch panel card, with a life of approximately 2.5 years. They
protect stored commands and pages against a power outage. The batteries are 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, and attach it to the panel for future reference.
Before replacing the lithium batteries, make sure you 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.
To replace the lithium batteries in the touch panel:
1. Discharge the static electricity from your body by touching a grounded object.
2. Disconnect all the connectors from the rear side of the touch panel.
3. Flip the touch panel facedown onto a soft cloth, and remove the Phillips-head screws from the
bottom panel. Then, gently remove the panel.
4. Gently rotate the circuit card backward until it lays down flat with the batteries exposed.
5. Using a nonconducting tool, carefully pry one battery from its socket and insert the new battery
observing the polarities indicated on the battery holder.
6. Rotate the circuit card back to the original position and place it in the touch panel housing. Do
not insert any the mounting screws.
7. Plug the AXlink and optional 12 VDC power supply connector back into the touch panel for
approximately 1 minute. Then, remove the connectors from the panel again.
8. Gently rotate the circuit card backward until you can lay it down flat with the batteries
exposed.
9. Using the nonconducting tool, carefully pry the other battery out of its socket. Then, insert the
new battery observing the polarities indicated on the battery holder.
10. Rotate the circuit card back to the original position and place it in the touch panel housing.
11. Place the bottom panel on the touch panel and align the mounting plate and screw holes. Insert
the four Phillips-head screws and tighten.
12. Plug all connectors back into the touch panel.

Static electricity can damage electronic circuitry. Before removing the touch panel
circuit card from the enclosure, discharge any accumulated static electricity from your
body and flat-blade tool by touching a grounded metal object.
