• Precautions
This mechanism unit uses a slide variable resistor to detect the height of the stage.
To absorb misalignment of the stage height due to unevenness of the DVD/CD mechanism unit and main unit, the
adjustment for each mechanism unit needs to be performed using semi-fixed resistors.
Because adjustment is performed on the production line, readjustment is not necessary usually. However, if an
elevation error occurs or when the slide variable resistor, spindle motor and CRG
chassis are replaced, elevation needs to be adjusted in the following procedures:
• Purpose
Adjust and check that the operation of elevation is normal.
• Adjustment method
• Measuring apparatus
Oscilloscope, L.P.F (one piece)
• Measuring point
EREF or EPVO
• Setting state
Without magazine, test mode
Place the DVD/CD mechanism unit facedown (place the DVD/CD mechanism unit so that
the main unit may be set to the upper side).
• Check procedures
For the flowchart of the test mode, refer to Page 76.
1. Enter the test mode and select a multiple DVD/CD player.
2. Set the mechanism unit test mode.
6.5 ELEVATION ADJUSTMENT
-
This adjustment shall be performed when an error code 84 is displayed for an elevation error.
