I'm trying to install my doorbell and always get error codes NC022 or NC023. I've already tried all troubleshooting steps but it doesn't change anything. I also tried resetting the doorbell to factory settings but pressing both buttons won't do anything (yellow light never shows).

Thanks for any help.

Hey there fmk, 

I'm so sorry for the late response, but I wanted to hop in here to provide some help. I understand getting error codes is not fun, and I'm happy to look into this for you. 

I would suggest running through this troubleshooter as it will provide you with the steps that you'll need to resolve the issue. 

Please let me know if you have any further questions or concerns.
