Scanner Diagnostics
The Scanner Diagnostics include separate tests to verify the operation of the front panel buttons,
LEDs, and the Alpha Wheel. For the K2600 keyboard models, the Scanner Diagnostics also
include tests for the keyboard, sliders, wheels, ribbons, and pedals.
Note: The Volume potentiometer is not tested using the Scanner Diagnostics.

To enter the Scanner Tests, first turn on the K2600R. Once the unit is on and in program mode,
simultaneously hold down the 4, 5, and 6 buttons located in the Data Entry section. All front
panel LEDs will light in a sequence, then simultaneously, and the LCD will display the
following:
