Thanks Jason/Lyndel. I appreciate your attempts to help me! I've been using Marantz RC5000i for years and am fully familiar with all the ccf files/codes available here, and have assembled several ccfs myself. I'm currently using a Marantz RC9200. The codes I'm in the process of aquiring are an alternative volume set (NOT the standard ones) for a Linn Klimax Kontrol stereo preamp. If you have these I'll be impressed, but as I say I know a bloke who does! I'm guessing he's having trouble locating where they're kept on his PC. It's the "raw" code entry method I need more info for. Once again, there must be a user manual for Touch screen setup - mustn't there ?!!
