5. Return the tonearm to the arm rest and fasten the

6. Since the tracking force is zero when the tonearm

is balanced level, turn just the tracking-foce scale ring in front of the counter-weight, and set the “0” on the scale to the index line on the shaft. When doing so, be sure to hold the counterweight with the other hand so that it does not turn together with the scale ring.
