Sorry if this post doesn't belong here. I am new here and trying to get my way around. I lost my marantz SR5000 product manual when i moved. The universal remote that came up with it is not working correctly. The remote doesn't work when i program multiple remotes (3) into it. I am thinking maybe a reset will help-erase its memory and start over - but not sure how. I took the batteries out for few mts but it still has the old settings saved.
