Battery Maintenance

If your Residential Gateway contains a battery backup feature, a high-capacity
rechargeable battery provides stand-by operation in the event of an AC power
failure. You can replace the battery without the use of any tools.
WARNING:
Fully charged high-capacity rechargeable batteries should be handled with
care. Replace only with the battery recommended by the manufacturer. Do not
disassemble it or attempt to recharge the battery outside the system. Do not
crush, puncture, dispose of in a fire, short the external contacts, or expose to
high temperature or immerse in water or other liquids. Dispose of the battery
in accordance with local regulations and instructions from your service
provider.
Charging the Battery
The battery begins to charge automatically as soon as you attach the Residential
Gateway to the AC electrical outlet. When you first plug in the Residential Gateway,
the POWER LED status indicator illuminates.
Important: It may take as long as 24 hours for the battery to charge fully.
Removing and Replacing the Battery
Under normal circumstances, the battery should last for several years. The
BATTERY LED status indicator blinks to indicate that the battery should be
replaced soon. Contact your service provider to obtain replacement batteries and for
disposal instructions.
Follow these steps to remove and replace the battery. You can remove and replace
the battery without disconnecting the AC power source.
Turn the Residential Gateway so that you are facing the side with the battery
1
compartment.
2 Gently release the latch to open the battery cover and gain access to the battery
compartment.
3 Grasp the plastic strip on the front of the battery and gently slide the battery
forward to remove it from the battery compartment.
4 Insert a new battery into the battery compartment. Do not force the battery into
the compartment, but be sure to press the battery all the way in until it seats
fully.
