When depressing the
tactile button
on digital controller,
nothing happens.
The tactile buttons under the overlay
may be not close enough to activate.
Same goes if the buttons are already
pressed by overlay without
depressing button.
Carefully (no too much at one
time
to avoid fracturing the traces on
the controller) tighten the nuts on
the back of the controller until
button activate. Same goes in
reverse if buttons are held down
