Thank you Andy & Terry for the apparent answer. That really helps a
lot. If I read that in the instructions, it sure didn't stick. I
would have thought that when I talked to the tech there that he would
have known that issue.
I appreciate everyone that replied on & off list for their time &
thoughts.
