door aside in a safe place.

3. Push the battery pack into the bay until it latches into place. The following diagram shows a
Telephony Modem with a 4.4 Ah lithium-ion battery pack installed. If you are taking the
battery out of the unit, make sure to use the battery pull strap to dislodge the battery.
Note: The Telephony Modem will not begin operating until you apply AC power.
4. Replace the door. To do so, place the tabs of the battery door into the slot on the
Telephony Modem battery compartment. Rotate the door toward the unit until the
latch snaps back into place.
Note: Since lithium-ion batteries contain precious material, there may be some benefit in
recycling. Please dispose of the battery responsibly and in accordance with local ordinances.
