Replacing The Batteries; Axt-Mlc (/Pb) Battery Replacement - panja Black/White LCD Instruction Manual

Replacing the Batteries

There are two lithium batteries on the touch panel card, with a life of approximately 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. You should write down the replacement date on a label by
adding 5 years to the date of installation, and attach it to the panel for future reference.
FIG. 1 Lithium battery and socket
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.
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.

AXT-MLC (/PB) Battery Replacement

Remove the lithium batteries from the AXT-MLC (/PB):
1. Discharge the static electricity from your body by touching a grounded object.
2. Remove the mini-XLR AXlink connector from the rear side of the panel.
3. Flip the touch panel face down onto a soft cloth, and remove the four Phillips-head screws
from the bottom panel; gently remove the panel.
4. Gently rotate the circuit card until you can lay it down flat with the batteries exposed. Then,
slowly rotate the circuit card backwards until you can lay it down flat with the batteries
exposed.
5. Carefully slide one battery out of its socket, and insert the new battery.
.
There is a danger of explosion if you replace the battery incorrectly. Replace the
battery with the same or equivalent type recommended by the manufacturer. Dispose
of the used battery according to the manufacturer's instructions. Never recharge,
disassemble, or heat the battery above 212 °F (100 °C). Never solder directly to the
battery or expose the contents of the battery to water.
6. Rotate the circuit card back to the original position and place it in the touch panel housing. Do
not insert any of the mounting screws.
7. Plug the mini-XLR AXlink connector back into the touch panel for approximately 1 minute.
Then, remove the connector from the panel again.
