4. Press key to set ELV/TRAY mode to TRAY.

5. Press key FF to release the clamp and return the tray to the magazine.

6. Press key to enter Elevation Move mode.

7. Use key FF/REV to operate elevation and set if to the graduation of the fourth step

(Fig. 1).

8. Make the adjustment. 

Use VR802 to adjust the difference in potential between EREF and EPVO to 0 ±20
mV.

9. When adjustment is completed, press key BAND to exit Mechanism Test mode.

10. Confirm operation of the mechanism.

Place the mechanism horizontally (CD core unit below). Take care not to short-cir-
cuit the PCB.

11. Confirm the height of the stage. Use the 4 key to select Disc No.4.

Check if the stopper bend of the clamp lever is engaged in the groove of the frame
stopper (Fig. 2-4).

Note :

The stopper bend will be pressed downward into the groove for final clamping. Confirm the engagement position
of the stopper bend.

If the stopper bend is engaged in the center and pressed downward, adjustment is completed. Go to step 15.

If the stopper bend is dislocated, check the amount of dislocation by following steps 12 to 14.
