g. The arm requires a l/--t"dia. mounting hole which can be located anywhere on snare with a radius of bid/'4"
from the center of the turntable. See figure 1- The arm-nest requires a 3,"16"dia. hole 5-1/2" forward ofthe
arm hole. Locate the arm-rest so that when the arm is on the rest. it will not interfere with placing a record
on the turntable. Provide a 1/4" hole for pickup wiring 1-1/4" left of the hole for the pickup arm.

l3. Provide a five terminal strip within 2" wiring distance of the 1/4" hole provided for wiring. The center
terminal must connect to the metal buseplate of the turntable assembly. therefore. a terminal strip with
center terminal used for mounting is satisfactory. Sec step 4 d-

2. Install arm-rest.
Use the 3/16" hole provided in step 1. Before tightening. rotate the arm-rest to align the open portion of
the "U" clamp with the final position of the pickup arm. See figure 1.

3. Temporarily install pickup arm. See figure 2.

nuts on the base mounting stud. below the turntable baseplate.

perly assembled. this retaining screw will extend into the base. under the pivot housing retainer and will
prevent lifting the housing off the base.

rest by pressing down on the arm.
