I am trying to get a function listed in my Arcam AVR300 manual's IR Remote Codes section working with my Harmony 885. The manual says the codes are based on the Phillips RC-5 standard. The commands I want to add are System Code 16 command Code 16 System Code 16 command Code 17 How knowing the codes do I then program them into the Harmony. They are not available as selections when setting up the AVR300 on the Harmony, thay are also not available on the original remote control to program from. Any help much appreciated.
