Questions and answers
why does my display keep flashing a phone receiver and how do I stop it
The flashing phone receiver icon on your BT 3510 indicates that the line is in use or a registration process is taking place. To stop it, check if another handset is using the line, ensure the phone is properly registered, and verify that the line is correctly connected. If the issue persists, try disconnecting and reconnecting the base unit.
