Replacing the Lithium Batteries
The AXB-232++’s lithium batteries have a life of approximately 5 years to protect its memory.
When DC power is on, the batteries are not used. When you install the AXB-232++, record the date
the batteries should be replaced.
Before removing the lithium batteries, contact your dealer and verify that they have a current copy
of your program to avoid an inadvertent loss of data and prevent an unnecessary service outage.
1.
Discharge the static electricity from your body.
2.
Unplug the two-pin power connector and any other connectors.
3.
Remove the two screws on the front panel.
4.
Remove the front panel, and slide the circuit board out of the enclosure.
5.
Carefully slide each battery out of its socket (FIG. 10), and insert the new battery.
6.
Slide the circuit board back into the enclosure.
7.
Replace the front panel and refasten the two screws.
8.
Reconnect any connectors that you removed.
There is a danger of explosion if you replace the batteries incorrectly. Replace
batteries with the same or equivalent type recommended by the manufacturer.
Dispose of the used batteries according to the manufacturer’s instructions. Never
recharge, disassemble, or heat batteries above 212°F (100°C). Never solder directly
to the batteries or expose the contents of the batteries to water.
