Installing the Battery
Installing the battery requires no tools. Follow these instructions to install the
battery.
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.
1 Turn the cable modem so that you are facing the side with the battery
compartment.
2 Gently release the latch to open the battery cover and gain access to the battery
compartment.
3 Insert the battery into the battery compartment. Do not force the battery into the
compartment, but be sure to press the battery all the way in until it seats fully.
4 Close the battery compartment door.
Important: After you install the cable modem and plug it into an AC electrical
outlet as described in Install the Cable Modem (on page 18), it can take as long as
24 hours for the battery to charge fully. However, you can begin using your
high-speed Internet and telephone service immediately after installation. See
Normal Operations (AC Power Applied) (on page 24) for information on how the
LEDs on the front of the cable modem indicate the state of the battery charge.
