Hi Dave,

I can not believe that a disk may damage the operating system of the Technics. I have never heard this in the last 25 years!

It is difficult to determine the error, if one has the KN 7000 is not directly in front of him.

You've successfully made the version 1.6. The version 1.6 will be shown to you on the screen?

You've made the big factory reset?:

You can also reset all the PERFORMANCE
items with the following procedure:
Turn off the power to this instrument once.
Then, while pressing the three lower left buttons
in the RHYTHM GROUP section (8 & 16 BEAT, ROCK & POP, BALLAD and JAZZ & SWING )
at the same time, turn the power on again.

You made the test: C # 3, D # 3 and C # 4 and found no errors?

What has not been done is the custom field that has not been touched by initializing.

You could even with the disk "INITIAL DATA DISK" initialize the custom field.

If this has not all been successful, the KN 7000 is a case for the service technician.
