I have completed partial setup of this remote by finding a working code. I bought the unit open-box so I never had an original remote. Nevertheless, the original remote is the one at this page ff that helps.
I'm missing the EQ button, SRS button and the Bass, Sub, and Treble up/down bottons.
Is there any way to guess the codes for the remaining functions, based on some of them working? Any other ideas besides buying the remote?
Thanks.

Edit
Further to my last question about guessing codes, I loaded up RMIR and looked at and saw this:

I have no idea what button 52-5f on the remote, so even if they are assigned I think they wouldn't be working. Could this be some of the missing commands? I'm thinking might be Bass+- etc.
If not, at least I see that they are all 3-digit codes less than 300. Would there be a way to test all of the number in that range somewhat automatically?
