Note: Batteries will not insert completely into the Telephony Gateway 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.
3. Push the battery pack into the bay until it seats into place. If you are taking the
battery out of the Telephony Gateway, position your finger in the battery
opening area and use leverage to dislodge the battery while pulling it
straight back.
Note: The Telephony Gateway will not begin operating until you apply AC power.
4. Replace the door. To do so, place the hinge tabs of the battery door into the receiver
slots inside the Telephony Gateway battery compartment on the opposite end of the
battery opening. Rotate the door toward the unit until the latch snaps back into place.
