Voice service.
Int rodu cti on
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.
Incorrect battery connection or replacement creates risk of explosion. Risk of
Energy Hazard, internal battery is 12VDC, 7.2 Ampere-hour. Before replacing
batteries, remove conductive jewelry such as chains, wrist watches, and rings.
High energy through conductive materials could cause severe burns.
The RG Battery Backup is intended for installation and operation in a controlled
environment (temperature controlled, indoor area free of conductive contaminants).
The unit shall be installed near an easily accessible power outlet.
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.
A
ll batteries used are sealed lead acid batteries. Battery should be recycled. Do not
dispose of batteries in a fire. The batteries may explode. Do not open or mutilate
