Thank you very much for your help. I am truly appreciative. However, the initial problem is still unsolved. Your solution got the speakers, which were functioning prior to my pressing the A/B button, to function again; and for that I am trully appreciative, but the speakers which were not functioning at that time, remain non functioning. (There are four speakers tied into the system. Two are on the 2nd level of my house. They were the only ones functioning before I pressed the A/B buttton and stoped them from functioning prior to my calling you; and now, because of your adviice, they are functioning again. However, two speakers remain non functioning. One is on the 1st level of the house and one is in the basement.) When the system was initially installed all of the speakers worked and they continually worked for a long time. But I stoped using the system for about four months and in that interim there was a power surge. Yet the system was and is protected by a surge protector. However after the interim period of non-usage, only the speakers on the 2nd level worked.. Then I pressed the A/B button, the rest you know.
Is there anything I can do to get all four speakers to work again? Again, I am appreciative of what you have done to this point.
When I press A and B together, only speaker B is lit. However. "Panel lock is on" is also lights up. What does "Panel lock is on" mean? What is a Panel lock? Should it be on, and is this part of my problem? How do I get the Panel lock off? And how do I get speaker A to light up?
Thank you. This reply will also accept your answers. I kept repeating your instructions and then improvising when they did'nt work. But at some point, something worked. I sent you a previous e-mail but I don't think you got it. At any rate, by reapeating your instructions numerous times and using some inprovisation of my own, I finally got all speakers to work. I think sp "B" controls the 2 upstairs speakers and "A" controls the one on the first floor and the one in the basement. Needless to say, I know I could not get them to work, again, should I undo what I've done; so I'm going to leave them alone, now. However, it would be great to be able to turn speakers "A" off when I want to, and speakers "B" off when I want to. Any final information you can give me in that regard might enbolden me to the point that I might, against my better judgment, try it. I 'm going to press the accept button, now, and thank you again.
