Replacing the Lithium Batteries

There are two lithium batteries (see FIG. 1 on page 5), with a life of approximately 5 years, on the
AXC-EM Master Card that protects stored commands if there is a power loss. The batteries are not
used when DC power is supplied to the cards via the AXB-MPE+. 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 AXB-MPE+
Static electricity can damage electronic circuitry. Before removing the lithium
batteries from the card, discharge any accumulated static electricity from your body
and screw-driver by touching a grounded metal object.
Before you replace the lithium batteries, verify that your AMX dealer has a current copy of control
commands stored in your AXB-MPE+. This will avoid any inadvertent loss of data or a service
outage.
You will need a flat-blade tool (non-conducting) that can be slipped under the lithium batteries to
pry them up and out of the sockets:
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 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.
1. Discharge the static electricity from your body by touching a grounded object.
2. Disconnect all the connectors from the back panel on the AXB-MPE+. Then, remove it from
the equipment rack (if applicable), and lay it down on a non-conductive surface.
3. Remove the two Phillips-head screws from the top panel on the AXB-MPE+, and slide the
panel backward to access the lithium batteries on the AXC-EM Master Cards.
4. Carefully pry one battery out of its socket and insert the new battery.
5. Plug the power supply back into the AXB-MPE+ for approximately 1 minute. Then,
disconnect the power supply again.
6. Carefully slide the other battery out of its socket, and insert the new battery.
