Hi Skip, try hooking up the remote to your computer wiht the provided software. It is actually quite easy to program. You can add customized buttons, re-label buttons, customize the individual screens, etc... You can also change the functions of the + and - buttons as well as the roller. Once you install the software and plug int the remote it is self explanatory.
Good Luck and email me if you have any questions. My home email is [email protected]
