A hard factory reset will return your device back to its original factory settings. This is useful as well if you need to return the device to pairing mode to add it to the Helix Pro mobile app. Please make sure to have the included reset pin with you to press the reset button on the doorbell.
Insert the reset pin into the reset hole on the back of the doorbell. Press and hold for 5 seconds until you hear that the reset is completed. The blue LED will be blinking.
Wait until you hear “Power on” indicating the doorbell has been reset and ready to add into the Helix Pro mobile app.
