Battery Installation and Removal
The TG1672 Telephony Gateway supports a Lithium-Ion backup battery to provide
continued telephone service during a power outage. The battery backup is not in-
tended to take the place of AC power.
The backup battery provides up to 12 hours of backup time, depending on model
and usage. It has a strap between the battery guides.
Your cable company may include a backup battery with your Telephony Gateway.
You can order batteries at http://yourbroadbandstore.com/
Note:
For safety and regulatory purposes, batteries are shipped outside of the
Telephony Gateway and must be installed.
