Your service provider may include a backup battery with your Telephony Modem. 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 Modem.
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.
