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 Removing and Replacing the Battery
later in this section. 
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 
REPLACE BATTERY LED status indicator illuminates to indicate that the battery 
should be replaced soon. Contact your service provide to obtain a replacement 
battery and for disposal instructions. 
Note: Follow the steps found in Removing and Replacing the Battery, later in this 
section, to remove and replace the battery. 
 
 WARNING: 
There is danger of 
explosion if the battery 
is mishandled or 
incorrectly replaced. 
Replace only with the 
same type of WebSTAR 
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.
