6.4 ADJUSTMENT 1 (LASER DIODE POWER ADJUSTMENT)

[Procedure]

(1) Check that "CD" is displayed on the FL display. If "CD-R" or "CD-RW" is displayed, press the ERASE button repeatedly until "CD" is

displayed.

(2) Press the RECORD button.

(3) Press the REC MUTE button. The LED for confirmation of LD emission will light in red. The LD is emitting in this status.

(4) Turn VR101 clockwise until the adjustment value to be reached is obtained.

(5) Press the STOP button to shut off the LD.

Note 1 : Attach the remote sensor of the laser power meter to a

point angled away about 10 degrees against the pickup
lens and where the maximum power is detected, so that
there will be no light reflected onto the pickup.

Note 2 : When adjusting with VRs, first turn them completely

counter-clockwise and then adjust clockwise, so that the
value to be reached is not exceeded.

Note 3 : The wave length setting of the laser power meter is
assumed to be 780nm.
