Quick update - Outlaw responded quickly to my problem and I have a new remote that works fine.
As bizarre as it may seem ( I swear I didn't do anything different ) the original "broken" remote mysteriously started working after I came back from a long weekend away. Before I got the replacement remote, every night I'd fiddle around with the remote that wouldn't work and never got it to perform - then I'm gone a couple of days, try it and Bingo! it works.
Outlaw had me send it back anyway when I told them.
I love the 990/7500 setup - outstanding!!
Thanks -
