Additional Notes:
- We highly suggest you attempt the primary wiring method before attempting this alternate method. This alternate wiring may cause a humming sound at your chime box.
- A 16V 10VA transformer is at the low end of the power supply spectrum. Wire age and other wiring conditions can affect how well it powers your Wyze Video Doorbell v2 or rings your mechanical chime.
- If you have 16V with a 10 VA transformer and this alternate wiring still doesn't help, you will need to replace the transformer with a higher VA transformer at your own expense.
- If you have 16V with a 10 VA transformer and this alternate wiring still doesn't help, you will need to replace the transformer with a higher VA transformer at your own expense.
Important: If you do not have an existing in-house chime or you are unsure of wiring, stop. Contact your local, licensed electrician for assistance.
