confirm that even if rotating the PITCH CON. KNOB, the PITCH value on the display
never varies.
4) Adjust R87 on the DD CAPSTAN PCB assy so that the “ PITCH ” value on the display
shows “ 0.0 ” ( “ -0.0 ” is no good).
5) Turn the FRONT/REAR SW to FRONT. Then, rotate and fix the PITCH CON. KNOB
at the center position.
6) Adjust R101 on the CONTROLLER PCB (there is a holl provided on the back side of the
Controller to rotate the pot) so that PITCH value shows “ 0.0 ” .
