NOTES ON ASSEMBLING THE MECHANISM

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 (0) 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.
