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.
Charging the Battery
The battery begins to charge automatically as soon as you attach the modem to
the 15 V DC power source. When you first plug in the modem, the
POWER
LED
status indicator illuminates.
Note:
It may take as long as 10 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

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
