The scan angle adjustment switch is located behind a !@4 -20 cover
screw (with gasket) on the back of the scanner. This cover screw is
necessary to maintain a NEMA Type 4 rating. After making the scan
angle adjustment, the cover screw must be tightened to 20 inch-lbs.

ATTENTION: The enclosure is not completely
sealed without the scan angle adjustment screw. Dust
and moisture may enter the enclosure causing
deterioration in performance.
