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.
