well i tried the cursor up-down advanced codes after using the 0004 device code and tried it like you said with the denon remote and here is something strange- i can use the curser up/down when i select ch.vol. with the denon remote but there is no tone control botton on the original remote so i pushed the tone control directley from the reciver but the cursor is not functioning on the bass/treble ??? is there any point of trying the efc and if so which sheet to use and how???
