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.
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-verseSM Voice service, including 911 dialing, will
not function without electrical or battery-backup power.
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.
