Hello!

I'm looking for discrete 5 digit codes for SONY RHT-G500 Home Theatre Stand.
The system uses Sony RM-ANU041 Remote.

I'm using One For All Kameleon 8 Gen III (8308) remote. Device codes 1759/1758 work, but both are missing essential "Levels mode" button, which sets up discrete channels volume. The system comes with unusably low central channel volume out of the box and I don't have the original remote to set it up.

Thanks in advance
