12. To see the amount of dislocation, place the mechanism upside-down. If the stopper bend has been dislocated in the direction of the first CD, turn VR802 to the left(Fig. 2). To lower the stage toward the twelfth step by 0.1 mm, reduce the voltage of EREF (adjusted in step 8) by 10 mV. If the stopper bend has been dislocated in the direction of the twelfth CD, turn VR802 to the right(Fig. 4). To raise the stage toward the first step by 0.1 mm, increase the voltage of EREF (adjusted in step 8) by 10 mV. 13. Place the mechanism horizontal. Go back to step 11 to reconfirm the stage height. 14. When adjustment of the stage height is completed, proceed as follows: 15. Press the EJECT switch. 16. Once operation of the mechanism has stopped, turn the power OFF.
