I'm still new at this so sorry if it has already been addressed. Had another question concerning remote EFC's. I was browsing through www.hifi-remote.com and their tables of Sony codes. I was able to find the codes listed for the Dream system I operate, but I'm having trouble interpreting how to use them. I am set up with Audio 1685. How do I configure the Command Codes for the buttons I wish to program in to the remote? The EFC's listed are all three digits and my remote uses 5 digit EFC's. I have heard that you can add two zero's to the beginning of each code to bring them to five, but I haven't had any luck with this method. Does the URC-8820 use it's own discrete EFC's? Any help would be appreciated.
