INSTALLATION AND ADJUSTMENT
A. Stylus Preparation
The stylus cannot be evaluated properly unless the stylus tip is clean. To
clean the stylus, use a camel's-hair brush (No.
2
size or smaller) dipped light-
ly in grain (ethyl) alcohol or alcohol-distilled water solution; one part alcohol to
three parts distilled water is recommended. (WARNING: Commercial record or
stylus cleaning solutions may cause corrosion and permanent stylus damage.)
The alcohol solution will remove any sludge deposits which may have coated
the stylus tip. The brush bristles should be trimmed to a length no longer than
6
mm
(1/4
inch). Always brush the stylus with a forward movement from the rear
(terminal end of the cartridge) to the front. Never brush or wipe the stylus from
front to back or side to side. NOTE: All Shure styli may be cleaned this way.
For other brands of styli, obtain manufacturer's procedure before using the al-
cohol solution, as permanent damage may result.
To mount a Shure stylus, depress the spring-loaded lever of the mounting
block and carefully insert the metal stylus housing (brass tubing) with the stylus
tip upward into the v-shaped groove in the top of the mounting block (see
Mounting Block illustration).
To mount other than Shure styli, place a piece of supplied pliable material
on the top of the mounting plate opposite the locating pin (see Mounting Plate
illustration). Place the stylus (tip upward) on the pliable material with the stylus
housing pointing toward the locating pin. Gently press the stylus grip
(not
the
housing) down into the pliable material so that the stylus tip is perpendicular to
the microscope objective lens.
