The arm lift height (distance between the stylus tip
and record surface when cueing lever is raised) has
been adjusted at the factory before shipping to ap-
proximately 5 to 10 mm (3/16” to 25/64").

on the market turn the adjustment screw clockwise or
counterclockwise, at the same time pushing the arm
