Chapter 2 Installing the DOCSIS Cable Modem

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.

1Turn the cable modem so that you are facing the side with the battery compartment.

2Gently release the latch to open the battery cover and gain access to the battery compartment.

3Insert 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.

4Close 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.
