Allen,

The setup code should be VCR 0618 for the RS 15-2104. See what that controls. If you want to move the buttons around or program commands from zhezhang's post use the column called EFC's they are synonymous with Advanced Codes. For detailed instructions on how to do that or anything else with you remote go to Rob Crowe's excellent unofficial website www.hifi-remote.com and look under manuals. If there is none yet for your remote use the RS 15-1994, I think it is similar. You can also double check the setup code there as well.

HTH,

Jon
