1. While pressing PAUSE and OPEN/CLOSE buttons on the main
unit, press "5" on the remote control unit.
2. Confirm that "J_xxx_yyy_zz" is shown on the front display.
For your information:

counter, while "zz" is the focus drive value.
Note:
Jitter value appears on the front display.

4. Adjust tangential adjustment screw so that the jitter value is
minimized.
5. Play test disc T43 (outer periphery).
6. Adjust tilt adjustment screw 1 so that the jitter value is minimized.
7. Play test disc T43 (outer periphery).
8. Adjust tilt adjustment screw 2 so that the jitter value is minimized.
9. Repeat adjusting tilt adjustment screws 1 and 2 alternately until
the jitter value is minimized.
