Installation, Connect to AC Utility Power

Installation

NOTE: Before installation, please inspect the RG Battery Backup. Make sure that nothing inside the package is damaged. The RG Battery Backup must be installed near the Residential Gateway and be easily accessible.

STEP 1:

Connect to AC Utility Power

Make sure that the power switch on the RG Battery Backup is in the OFF position. Plug the AC cord on the RG Battery Backup into a wall outlet.

STEP 2:

Connect to the Residential Gateway

Connect the DC plug on the RG Battery Backup into the Residential Gateway.

STEP 3:

Turning on the RG Battery Backup

Turn the switch on the RG Battery Backup to the ON position. The “ON A/C” LED light should illuminate. Note that the “Testing Battery” LED will ﬂash for ﬁve minutes as the unit performs a self-test. This is normal.

NOTE: It takes approximately 18 hours to charge a new, fully depleted battery at normal indoor temperatures. If a power outage occurs before the battery is fully charged, the battery-backup time shown on page

11 will be reduced. Therefore, you should not rely on battery-backup power for at least 18 hours after your RG Battery Backup is initially installed or a replacement battery is thereafter installed. During these periods especially, and at all other times in general, you should ensure that you have an alternative means of dialing 911, such as via a cellular telephone. Your AT&T U-verseSMVoice service, including 911 dialing, will not function without electrical or battery-backup power.
