I didn't see a response back from my original question, but I wanted to send the following before I take a break for the evening - so you would have it.
This is a link to the electronic (PDF) version of the manual for your system, and a few other slightly different models (see the first page). You should be able to click the link below and have the manual appear on the screen or be downloaded to your computer.

If you have any trouble viewing that manual, you may need to install a PDF viewer on your computer. If you need such a program, I have a link to a no-cost viewer below. Just make sure you UN-check the "Optional offer" BEFORE clicking the "Install Now" button

I hope this helps. Please let me know if you have any trouble with those links or any other questions.
If this has answered your question(s), please take a moment to rate MY service level (Excellent is my goal) so that I get credit for helping you with this question.
You should see some "stars" to do that, but please let me know if you do NOT see them (you may have to scroll UP or DOWN) or can not use them.
Thanks, ***** *****
