Hi Warren, I share your frustration but got around it by buying the Logitech Harmony 350 remote - it’s their basic programmable remote and cost me £40 in the UK. You do need to configure it to use DCS codes but this is quite simple and once done it works perfectly - I can change volume more accurately, power the unit up and down, mute, pause, play, skip, change input. It’s made it much easier to operate. I have a Bartok btw.
Regards, Mike.
