9. Operation check Terminate the test mode. Place the mechanism unit horizontally (set the main unit to the drop side). At this time, take care of short-circuiting of the PCB. 10. Check the height of the stage. Press the DISC ± key to select DISC 4. Check that the stopper bend of the clamping lever is fitted in the groove of the frame stopper section. (Fig. 3 to 5) � Precautions � The stopper bend to be clamped finally is clamped under the groove. Check the stopper bend at the position where it is fitted in the groove. � Adjustment is completed if the stopper bend enters the center and is clamped under the groove. Go to 14). � If the stopper bend is dislocated, check misalignment. Go to 11). 11. If the mechanism unit is dislocated: Place the mechanism unit facedown. When the mechanism unit is dislocated to the direction of the first disc, turn VR302 counterclockwise. (Fig. 3) Drop the voltage of EREF by 20 mV which was adjusted in 7. to descend the stage to the direction of the sixth disc by 0.1 mm. When the mechanism unit is dislocated to the direction of the sixth disc, turn VR302 clockwise. (Fig. 5) Raise the voltage of EREF by 20 mV which was adjusted in 7. to ascend the stage to the direction of the first disc by 0.1 mm. 12. Place the mechanism unit horizontally and recheck from 10. 13. After adjustment has been completed, 14. Press the EJECT switch. 15. After the operation of the mechanism unit has stopped, turn off the power. 16. After the power has be turned off, turn on the power in one minute or more and insert the magazine. 17. Check that the mechanism unit operates normally for the first and fourth discs. 18. Terminate all adjustment for OK (normal operation) and readjust for NG (abnormal operation).
