Memory Lithium Battery Condition Test

...................................................................................................
If the start-up tests detect that the voltage level of a lithium backup battery on the
MCB Office is insufficient to reliably maintain the memory contents in the event of
power failure, the following message will appear:
MCB Office - BATTERY LOW
This message indicates that the MCB Office card battery has an insufficient voltage
level. In this event, the Coral system database is in jeopardy of being lost during a
power failure. If this message appears, the database should be saved and the battery
replaced at the first opportunity.
To ensure that the system database is not lost, save the database to the IMC8 card via
the database control branch of the system database (ROUTE: ROOT, 0, 10, 2, 2, 0) . For
Saving to IMC8, page
details, see
and the database is lost from memory, the system will copy the database from the
IMC8 card into database memory as the system restarts.
Once the system database is safely saved on the IMC8 card, power to the Coral system
may be turned off at a time that will cause the least disruption of service to the user.
At that time, the battery on the MCB Office may be replaced and the system restarted.
To replace the lithium battery, carefully raise the battery holder clip and then
insert the new battery with the + (positive) symbol appearing on top. Do not
apply too much pressure to the battery holder clip as this could cause the
clip to snap.
Explosion and Environmental Hazards.
There is a danger of explosion if the battery is replaced incorrectly.
Replace the battery only with the same or equivalent type recommended by the
manufacturer.
Dispose of used batteries according to requirements specified by the battery
manufacturer and/or local regulatory agencies.
