I've had issues getting this to work using my new hummy, worked fine on my 9300t ( for sale !) Anyway I cleared all stored commands on the SAT key using: - Press MAGIC until the light blink twice. - Press 976 and the light should blink twice. - Press two time SAT (SAT, SAT) the light should blink twice. The reprogrammed it using code SAT 1176 This gave me 90% of the remote functions. Manually I got the 7555 to learn the other commands from the hummy remote. Seems to be working well !! All this so I could have volume pass through.
