My NUTONE doorbell does not work,is there any way to change batteries??
Also I have a videoman camera at the door that is dead too,
Please help me find a solution as nobody who rings the bell is being listened

First question: Are you sure it a battery operated Nutone system? Can you get us the mode number?

To be bluntly honest, telling us something is broke without any information as to the reason you believe it to be broke is an exercise in futility. Does the camera show any image at all? Is/Are the cable(s) connected properly? Is there power going to the camera? What is the camera connected to, a TV, PC or tablet? Are they in good working order.

Can you please give us a little assistance, Patricia?
