Your caption phone has a built-in light bar on the top of the phone.
This flashing light will help you stay connected by notifying you of incoming phone calls in case you don’t hear it ring and show you that you have new voicemail messages.
The light will stop flashing and remain lit up when you answer the phone.
The light will also flash if you have a missed call. If the caller leaves a voicemail, a small red dot will appear above the Voicemail icon. Once you listen to your new voicemails, the flashing will stop.
