Residential Gateway  
(RG) Battery Backup  
BU3DC000-12V  
User Manual  
 
Introduction  
Thank you for purchasing the Residential Gateway (RG) Battery Backup.  
Natural and man-made power disturbances can disrupt the power supplied  
to your home electronics. These power problems can disrupt the normal  
operation of important electrical equipment and related services.  
Battery Backups provide an uninterruptible power supply (UPS) to keep  
critical systems up and running in the event of a power loss. This RG Battery  
Backup, once properly installed and used, has been designed to maintain  
SM  
your AT&T U-verse Voice service in the event of a short disruption to your  
commercial power service.  
Safety Information  
CAUTION  
Internal battery voltage is 12V DC.  
Incorrect battery connection or replacement creates risk of explosion.  
The RG Battery Backup is intended for installation and operation in  
a controlled environment (temperature controlled, indoor area free of  
conductive contaminants).  
No user-serviceable parts exist inside the unit. Refer repair issues only  
to qualified personnel. Fuses or other parts must be replaced ONLY with  
parts of identical types and ratings. Substitution of non-identical parts  
can cause fire and other safety hazards.  
All batteries used are sealed lead batteries. Batteries should be recycled.  
System Requirements  
The RG Battery Backup is designed for use with the AT&T U-verse  
SM  
SM  
Residential Gateway and your AT&T U-verse Voice service.  
SM  
NOTE: Your AT&T U-verse Voice service, including 911 dialing, will not function without electrical or  
SM  
battery backup power. The RG Battery Backup supplies power for your AT&T U-verse Voice service; it  
does not supply power for cordless phones (and it does not supply power for your network interface device  
or optical network terminal, typically located on the outside of your home, which may also require battery  
SM  
backup power for your AT&T U-verse Voice service to function). Therefore, in the event of a power outage,  
you should ensure you have one corded single-line, touchtone phone connected directly to the AT&T  
SM  
SM  
U-verse Residential Gateway or your in-home wiring and the AT&T U-verse Residential Gateway  
SM  
connected to the RG Battery Backup. (Rotary/pulse phones do not work with AT&T U-verse Voice service.)  
If you connect more than one corded phone, it will use more power; if you connect a cordless phone, it will  
not function without a separate battery backup, and not all cordless phones are so equipped. If you have a  
monitored home alarm, you should never plug a multi-line phone directly into the Residential Gateway—it  
could interfere with the alarm signals. You should not connect the RG Battery Backup to any device other  
SM  
SM  
than the AT&T U-verse Residential Gateway or use it with any service other than your AT&T U-verse  
Voice service, and you should always have an alternative means of dialing 911, such as via a  
cellular telephone.

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  
SM  
telephone. Your AT&T U-verse Voice service, including 911 dialing, will  
not function without electrical or battery-backup power.

Operation  
Turning off the RG Battery Backup  
Turn switch to OFF position. The “ON A/C” LED light should turn off.  
To Silence Audible Alarm  
Turn mute switch to ON (down) position.  
To Conduct a Self-Test  
Use the self-test to verify both the operation of the RG Battery Backup  
and the condition of the battery. Turn the mute switch ON then OFF,  
then ON and OFF again within five seconds. During the self-test, the RG  
Battery Backup operates in backup mode.  
The RG Battery Backup automatically conducts a self-test every 21 days.  
NOTE: During the self-test, the RG Battery Backup briefly operates  
on battery-backup power. The “Testing Battery” LED will flash for five  
minutes during the test period. If the RG Battery Backup passes the self-  
test, it returns to online operation. If the RG Battery Backup fails the self-  
test, it immediately returns to online operation and lights the “Replace  
Battery” LED. The loads are not affected. Recharge the battery overnight  
and perform the self-test again. If the “Replace Battery” LED is still on,  
the battery needs to be replaced.

Wall-Mounting Instructions (Optional)  
NOTE: Required hardware not included. Refer to the wall-mount instructions  
for required tools and materials.  
STEP 1: Position the template on the wall where you  
want to mount the RG Battery Backup and  
tape in place.  
STEP 2: Make a mark on the wall in the 2 screw locations  
indicated on the template. Remove the template  
from the wall.  
STEP 3: Use a drill to drill holes where you made the  
mark on the wall. If you drill into a wall stud,  
proceed to Step 5. If not, go to Step 4.  
STEP 4: Insert anchor(s) into the hole(s).  
STEP 5: Screw in the screw, leaving it protruding  
1⁄4 inch from the wall.  
STEP 6: Mount the RG Battery Backup on the screw heads.

Battery-Replacement Procedure  
The RG Battery Backup is designed with an easy-access battery door.  
Replacement of the battery requires removing the battery door on the rear of  
the device.  
No tools are needed.  
STEP 1:  
Turn off power switch. Disconnect the RG Battery  
Backup from power and any connected devices.  
Remove the battery door on the rear of the RG Battery  
Backup by pressing the tab on the top of the battery  
door and pulling outward.  
STEP 2:  
Remove the battery from enclosure; remove the wire  
connections from the battery.  
STEP 3  
Connect the new battery (black-to-black, red-to-red);  
place the battery into enclosure.  
WARNING: Carefully connect the wires to the correct  
terminals. The red (+) wire is labeled with a tag. The  
replacement battery will have color-coded terminals  
(red = +, black = -). Do not misconnect the wires.  
STEP 4:  
Securely reconnect battery door.
