Troubleshooting

Turntable does not operate

1.

Make certain the turntable’s AC cord is plugged into an
AC outlet, and that the AC outlet is “live.”

2.

Check the drive belt to make certain it is on correctly.
(See Figure 10.)
A) Remove the record mat from the turntable platter
(Fig. 10a). Place the mat in the cardboard packaging
sleeve for safekeeping. Through an opening in the
turntable platter, visually inspect to see if the drive belt
is around the motor pulley (Fig. 10b).

B) If the drive belt is not around the motor pulley: Lift
and remove the turntable. Place a thumb into each of
the left and right openings on the turntable platter; and,
using the fingers to press down on the turntable hous-
ing’s surface, pull the platter 

straight up

(Fig. 10c).

Avoid pressing on the tone arm.

C) With the turntable platter bottom side up, place the
belt along the outside wall of the turntable platter's
drive rim, making certain that the belt is smooth and
flat all the way around (Fig. 10d).

D) Put the turntable back on the center spindle, make
certain it is fully seated, and align one of its openings
over the motor pulley position.

E) Through the opening, carefully hook the turntable
belt with a finger or with the original red ribbon (

never

use a sharp object) and pull the belt over the motor
pulley (Fig. 10e). Make certain the belt is not twisted
between the pulley and the platter’s drive rim.

F) Put the record mat back on the platter.

G) While holding the tone arm in its rest position, 
slowly turn the platter by hand clockwise at least 10
rotations to clear the mechanism’s automatic cycle.
