indicate current AFTER TOUCH value).
Calibration Complete.
Press SHIFT + STEP to conrm and save all calibration results. Region B LED will show calibration results. Relative LED
will light to indicate corresponding channel is calibrated. Otherwise it may be a failed calibration.
NOTE: Press SHIFT + KYBD will cancel all calibration and return to normal mode.
TIPS:
A. You can calibrate only one of the channels (1-3) at a time.
B. For channel 4 and 5, you have to calibrate both of them simultaneously.
