How Do I Maintain the Battery?
Your modem includes 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:
There is danger of explosion if the battery is mishandled or incorrectly
replaced. Replace only with the same type of battery. Do not disassemble it or
attempt to recharge the battery outside the system. Do not crush, puncture,
dispose of in a fire, short external contacts, or expose to water or other liquids.
Dispose of the battery in accordance with local regulations and instructions
from your service provider
.
Charging the Batteries
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

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 Batteries.

If you choose to operate your modem without a battery, you risk losing
your telephone service during a power outage.
Replacing the Batteries
