PC2R Rack Models

The Scanner Tests for the PC2R rack model include separate tests for the front panel buttons and
LEDs, rotary potentiometers including Knobs A–D and Volume, and the Alpha Wheel.
To enter the Scanner Tests, first turn on the PC2R. Once the PC2R is on and ready to play,
simultaneously hold down the three buttons located in the top row of the Modes section
(Internal Voices, KB3 and MIDI Setups). All front panel LEDs will light in a sequence and the
LCD will display the following:

The first line of the display shows the scanner software version, the battery voltage and the
current value for the Mod Wheel position. Disregard the Mod Wheel value; it is applicable only

result of the volume potentiometer test.
To exit the Scanner Tests and return to normal operation, simultaneously press the Cancel and
Enter buttons.
