How Do I Maintain the Battery (Optional Model Only)
How Do I Maintain the Battery (Optional Model Only)
Your modem includes one 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 a 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 the 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 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 27).
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 27),
to remove and replace the battery.
