TM822G Basic Battery Installation and Replacement
This model of the Telephony Modem has the ability to provide battery backup in
the event of a local power loss. The battery backup is not intended to take the place
of AC power.
Use this procedure to install and to replace the backup battery.
1
Press down and pull back on the latch holding the battery door (on the bot-
tom of the Telephony Modem). Pull the door toward you. Set the door aside
in a safe place.
CAUTION
Risk of equipment damage
Improperly inserting the battery may damage the battery connector in
the Telephony Modem. Carefully follow the instructions in the next step
to avoid damage.
2
Hold the battery pack so that the guides on the battery align with the slots
on the Telephony Modem and slide the battery into the bay. The diagram on
the left shows the proper orientation.
Note
: Batteries will not insert completely into the Telephony Modem if not
oriented correctly. The battery should slide into the bay without significant
force. Line up the guides on the battery with the slots in the battery bay.
