JBean,

I could not get night mode to set on the main phone with the night mode button.

I moved the phone with the night mode and plugged it in at my desk.

It will not give a normal dial tone when attempting to make an outside call.

However, I was able to set the night mode while it was plugged in at my desk (it would not register at the phone's normal place where it is plugged in).

With the night mode light lit up, I can hear incoming calls.

With the night mode button off (no red light) I cannot hear incoming calls. They go straight to voicemail.
Isn't that backwards?

Do you suppose the problem is with the actual phone itself rather than wiring or a setting somewhere?

My phone, when plugged in to the wall outlet where the night phone normally is, will give a normal dial tone there. But the night phone one will not.

Thanks much for your assistance. This phone set up far exceeds our needs in a 2 person office!
