2.2 Ah 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. The 2.2Ah Lithium-Ion battery pack can be inserted into the Telephony
Modem. Use this procedure to install and to replace the backup battery.
Action
1 Insert a finger into the latch opening, press down and pull back on the latch
holding the battery door (on the bottom of the Telephony Modem). Pull the
door toward you. 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. The battery will not insert completely
into the Telephony Modem if not oriented correctly.
