(3) Ignite the searchlight and direct the beam toward a relatively flat, vertical surface approximate-
ly 100 feet away.
(4) Swing spherical link downward away from the motion transfer arm. Physically move the motion
transfer arm to obtain the desired beam pattern. Adjust the position of the spherical link until
the retaining screw passes through the link and into the motion transfer arm without changing
the position of the motion transfer arm.
NOTE
Several trial adjustments of the spherical link may be necessary to obtain the desired
narrow-to-wide beam spread pattern.
