Examine
the wiring
to the
buttons.
High
1. Remove the rear panel of the
console.
2. Examine the wire inputs to
connector J13 on the control board.
If any wires are loose, tighten the
screw terminals.
3. Using a continuity tester, measure
the resistance between terminals 1
and 2 when Feed Hold is pressed
and 3 and 4 when Cycle Start is
pressed.

If there's continuity at the
terminals on the control board
and the buttons still don't work,
examine the USB cable to the
control board.

If there's not continuity at the
terminals when the buttons are
pressed, remove the lower rear
panel of the console and examine
the screw terminals on the rear
of the buttons themselves.
Shipping can sometime cause wire
terminals to become loose. Re-seating the
wires will usually fix non-responsive
buttons.
If you have tested all terminals and the
buttons still don't have continuity when
pressed, replace the buttons:
