1. Fasten Screw A so that the interval (a) will be about 5.2mm
and the interval (b) will be about 2.6mm. (The interval (a)
can be measured using a pair of vernier calipers or similar
tools.)
2. Turn B so that Position (c) will come at about the center of
interval (d).
3. Then, play the test disc and fine tune A or B so that the jitter
value would be minimized.
