Battery Installation and Removal
The TG862 Telephony Gateway supports a Lithium-Ion backup battery to provide
backup in the event of a local power loss. The battery backup is not intended to take
the place of AC power.

Telephony Gateway and must be installed.
The TG862 supports the following battery models:
• Basic backup battery — provides up to 5 hours (black) or 8 hours (grey)
of backup time, depending on your Telephony Gateway model and usage. It
may be light grey (recommended battery) or black.
