Install the Battery
Your residential gateway may include one rechargeable Lithium-Ion battery to
provide stand-by operation in the event of an AC power failure. In the event that
you ever need to replace this battery, contact your service provider.
It is possible to use the residential gateway without the battery. However, if you
choose to operate the residential gateway without a battery, you will not have
telephone service during a power outage.
For information on battery maintenance, refer to Maintaining the Battery (on page
41).
Installing the Battery
Installing the battery requires no tools. Follow these instructions to install the
battery.
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.
1 Turn the residential gateway so that you are facing the side with the battery
compartment.
2 Gently release the latch to open the battery cover and gain access to the battery
compartment.
