How do I verify the status of my battery?

There is an indicator light on the front of your telephone modem

  • A solid light indicates the battery is in good condition and fully charged.
  • A blinking light indicated your battery is charging.   If the light continues to blink after 8 hours, your battery may be weak and may need to be replaced.
  • If the battery light is out on the modem device, your battery may be missing, depleted, or not correctly installed.
  • If an external battery/UPS is in use, please refer to the manual for that device.
