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.
The RG Battery Backup shall be installed near an easily accessible power
outlet.
Introduction
This Residential Gateway (RG) Battery Backup, once properly installed and used,
has been designed to maintain your AT&T U-verse® Voice service in the event
of a short disruption to your commercial power service.
Safety Information
CAUTION
System Requirements
The RG Battery Backup is designed for use with the AT&T U-verse Residential
Gateway and your AT&T U-verse Voice service.
NOTE: Your AT&T U-verse Voice service, including 911 dialing, will not function
without electrical or 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-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 U-verse
Residential Gateway or your in-home wiring and the AT&T U-verse
Residential Gateway 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 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.
