Modem and must be installed.

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 batteries.
Actions
1. Press the tab and slide the door. Pull the door toward the back of the
Telephony Modem until it detaches. Set the door aside in a safe place.
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 slots in the battery bay with the guides on the battery and
apply even pressure on both ends of the battery.
