If the zoom control acts in the wrong
direction, move the zoom stick up-
wards and press ADJ-DIR.

rect (issue: the zoom motor moves
without pressing the stick), leave the
zoom stick in its center position (do
not touch it) and press ADJ-0.

to check if the engravings on the Knob Calibration Ring
align with the corresponding values on the WCU-4 screen. If they
do not align, press the

soft button to start the knob linearizing
procedure.

all previously stored alignment points will be
