How Do I Maintain the Battery? (Optional)
Your modem may include a rechargeable Lithium-Ion battery to provide 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 modem to the
AC electrical outlet. When you first plug in the modem, the POWER LED status
indicator illuminates.
Important: It may take as long as 24 hours for the battery to charge fully.
Using the Modem Without a Battery
If you want, you can use the modem without a battery. If you need to remove the
battery, follow the procedures found in Removing and Replacing the Battery
(on page 31).
Important: If you choose to operate your modem without a battery, you risk losing
your telephone service during a power outage.
Replacing the Battery
Under normal circumstances, the battery should last for several years. The
BATTERY LED status indicator turns off to indicate that the battery should be
replaced soon. Contact your service provider to obtain replacement batteries and for
disposal instructions.
Note: Follow the steps found in Removing and Replacing the Battery (on page 31) to
remove and replace the battery.
