Hi again

I spent a fraught couple of hours with my 5000C in this condition, and no amount of plugging/unplugging, re-configuring or resetting worked. As I mentioned, I'm pretty sure I had to disconnect all comms lines, and power up from the rear with the MSR pointing at the display and the number 6 depressed to reset it to Type 6 (as you will need for use with the G68). This got it out of the Test mode, but I lost all the settings and had to start again. If I remember correctly, I had gone into the Test set up to make an adjustment to the tweeter level, and that's when I found myself trapped!

Cheers

George
