3.
Rotate the platter so that the one of the holes is aligned with
the Start/Stop button on the front corner of the turntable. The
brass motor spindle should be visible through this hole.
4.
Reach into the hole and pull the rubber drive belt off of the
inner ring, and install it over the motor spindle. Be careful not
to twist the rubber drive belt during this step. Check to make
sure the platter rotates uniformly. If the drive belt is properly
installed, there should be a slight amount of tension that
brings the platter to a stop after spinning it freely.
TONEARM SETUP
1.
Begin by rotating the counterweight counter-clockwise until it is in the
complete forward position (NOTE: this is also the maximum amount
of pressure that can be applied to the cartridge.)
2.
Now there should be a feeling of weight and resistance when the head
shell is raised and lowered. Begin rotating the counterweight
clockwise (away from the pivot point) until the weight and resistance
feeling is gone. If done properly, the tone arm will pivot with very
little resistance back and forth indicating that there is exactly 0 grams
of stylus pressure.
3.
With the counterweight in its new position further away from tone
arm pivot point, grasp the scale ring of the counter weight and rotate
it until "0" is in the vertical position.
4.
Finally, rotate the counterweight (and scale ring) counter-clockwise
(towards the pivot point) until the desired amount of weight is
reached. If the scale rotates 360 degrees beyond the zero point, the
new scale ring reading should be added to 3.5.
*The included head shell and cartridge assembly requires a minimum
of 3 grams and no more than 5 grams for optimum performance.
