Diagnosis
The reset procedure requires precise timing while the unit is powered. A common mistake is not holding the button long enough.
How to Fix It
The correct sequence is: Ensure the Chime Pro is plugged in and powered. Locate the recessed reset button on the back. Use a paperclip to press and hold the button firmly. You will see the light on the front turn off. Continue holding the button for 15 full seconds. Release the button. The light will flash a few times and then become a solid white light, indicating it is in setup mode and has been reset.
If That Didn't Work
If the light does not respond, perform a power-cycle reset. Unplug the device. Hold the reset button down. Plug the device back in while continuing to hold the button. Hold for an additional 15 seconds, then release. This forces a reset during the boot process.
Heads Up
A factory reset removes the Chime Pro from your Ring account and deletes its Wi-Fi configuration. You will need to set it up again as a new device in the Ring app. Any custom chime tones linked to it will be lost.
