Scanner Tests
PC2 Keyboard Models
The Scanner Tests for the PC2 keyboard models include separate tests for the front panel buttons
and LEDs, front panel sliders including the Master Volume slider, the Alpha Wheel, the Mod
and Pitch wheels, the keyboard, and the pedals.
To enter the Scanner Tests, first turn on the PC2. Once the PC2 is on and ready to play,
simultaneously hold down the 4, 5 and 6 buttons. All front panel LEDs will flash and the LCD
will display the following:
Figure 5-3 LCD example, PC2 scanner tests
The first line of the display shows the scanner software version, as well as the battery voltage
and the current value for the Mod Wheel position. The second line shows the results of the
current test. Figure 5-3 shows the result of a key test—in this case striking the key C4 on the
keyboard.
To exit the Scanner Tests and return to normal operation, simultaneously press the Cancel and
Enter buttons.
Front Panel Buttons
To test a button, press any front panel button. An example of the expected test result for the Solo
button follows:
BUTTON Solo
Alpha Wheel
To test the Alpha Wheel, turn it to increase or decrease the value by one. The expected test result
when the Alpha Wheel is turned is one of four values–0, 1, 2, or 3:
SPINKNOB = 3
Front Panel Sliders
To test the front panel sliders, move a slider to check its value at the bottom, center, and top. An
example of the normal test results for the Slider A follows (your results may vary slightly):
At bottom: SLIDER 1 = 0
At center: SLIDER 1 = 128
At top: SLIDER 1 = 255
SCAN1.3 B=2.9 W=128
