Performing Lens Calibration

a lens unit, perform [LENS CALIBRATION] by holding to press
ZOOM/L-CALIB. button on the cabinet over two seconds.
Calibration corrects the adjustable zoom, shift, and focus
range. If calibration is not performed, you may not be able to
get the best focus and zoom even if you adjust the focus and
