Going back to Bruce's earlier question, was the 818 Typed according to the instructions on page 30 in this user guide?

As I recall, mine wouldn't show MQA in the display until I did this, even though I had installed the v4.00 firmware. I was testing the USB input at the time, but I just confirmed I can get MQA to work with files from the MD600 going to the ID41.
