The alternate hard reset procedure is:

1. Turn the Kurzweil off

2. Hold down the KEY START, KEY STOP, and LAYER VOLUME buttons for 5 seconds while powering the unit up, then release

3. Select RUN DIAGS

4. Press the UP arrow until the display reads RAM TEST

5. Press the START/STOP button to run the test

6. When the display reads SUCCESS, turn the unit off and back on. The unit is now reset.

If your Kurzweil still does not come up to the normal screen after this procedure, it will require service.
