Hi all,

Just joined as we purhcased a Panasonic TDA30 and TVM50 for our Legion hall.

I know the post is dated a bit but my .02 cents here:

I had the same problem and just *790'd the ext.

The power fluctuated quite regularly here recently due to new heavy construction in our area. (Which will call for a UPS).

I noticed a few phones doing this after some bouncing of the mains.

Hasn't done it since but I believe that was what has caused the phantom message waiting light to come on some sations.
