Thank you, XXXXX XXXXX have handbook. But cannot find answer to problem which is malfunction which takes various forms and can be reduced by constant Auto Tuning. A red XP is almost always showing on the little screen on the set and seems to be the explanation to the difficuoties. I cannot get it to go away.
No. i have just gone through all functions and they all now work correctly (other than I have lost all recordings but that is not unexpected after I chose return to factory settings i suppose). So OK now. But the red XP is still showing!
