Battery Installation and Removal
Introduction
The TG862G Telephony Gateway supports a Lithium-Ion backup battery to provide continued
telephone service during power outages. The battery backup is not intended to take the place
of AC power.
Note: The battery is intended only to provide emergency telephone service in the case of a
power outage. Wireless data and wired data service will not be available during a power
outage. In addition, LED operation is reduced when the Telephony Gateway is operating on
battery power.
Note: For safety and regulatory purposes, batteries are shipped outside of the Telephony
Gateway and must be installed.
The TG862G supports the basic backup battery, which provides up to 8 hours of backup time,
depending on model and usage.
Basic Backup Battery
See Basic Battery Installation and Replacement (page 16).
Your service provider may include a backup battery with your Telephony Gateway. If you wish,
you can purchase an additional battery at http://shop.surfboard.com/. The website will list the
recommended battery type for your Telephony Gateway.
Note: The backup times shown here are only an estimate and assume that your battery is fully
charged. If your battery is partially discharged (for example, if it is in the middle of a self-test
or is not yet fully charged), then your backup time will be reduced.
