How can I check to see if my Home Phone modem (eMTA) backup battery is working? :


An indicator light on the front of your modem lets you know that your battery is charged and operating properly. To check its condition:

  1. Unplug the modem power cord from the wall.
  2. Verify that you have a dial tone on your TWC Home Phone.
  3. If you do, your battery is working.
