We have had several situations where the K2000 serial number is not an accurate method of determining if the K2000 is Calvin or Janis. We have shipped several customers Janis when they needed Calvin and vise versa.

We have determined a new method to determine if the unit is Calvin or Janis.

(1) Turn the K2000 off
(2) Press the "1", "2", and "3" buttons on the Kurzweil and while holding the buttons down turn the power on.
(3) When you see a screen appear on the display let go of the "1", "2", and "3" buttons.
(4) The screen will read " HARD RESET" and under that " DIAGNOSTICS". Move the cursor to highlight "DIAGNOSTICS" and press the "Enter" button.
(5) The K2000 will now be in the self diagnostics mode. There will be 3 columns of diagnostic tests and there is a test in the middle column that tests the Calvin / Janis chips. It is the fifth test down from the top right under the SCSI test. If the screen says " Calvin and Hobbs" the machine is a Calvin. If the Screen says "Janis and Hobbs" the machine is a Janis.
(6) Once we determine the correct software simply power the machine off and back on again and the unit will be back in its normal play mode but it will be set to factory new condition. Any programs in PRam will be erased.



The Janis chip replaces the Calvin chip. This is the "sample fetch" chip used by the K2000. Kurzweil made the change as part of a manufacturing update. In terms of the results for the end user, there is no difference in features or capability. However, because of differences between the two chips, the Janis chip requires a slightly modified circuit board and engine firmware. You can tell what kind of board you have by whether or not there is a J after the version number displayed on power-up. If you are updating your unit to a new version of the operating system, you will need to know which version you have so that the proper engine firmware will be sent. There is no damage caused by installing one version of firmware in the opposite machine; it will simply not work.
