Precautions on Adjustment
1.
Adjustment data
The adjustment data for the drive block are recorded to the IC4302
on the VC-520 board.
These data cannot be read or written from the adjustment remote
commander or SeusCam, unlike the camera and LCD adjustment
data.
Accordingly, be sure to adjust all items of the drive adjustment
when the following parts were replaced:
•
Drive block
•
Mounted VC-520 board
•
IC4101 (RF process) on the VC-520 board
•
IC4201 (DVD DSP) on the VC-520 board
•
IC4401 (DVD mecha drive) on the VC-520 board

Order of adjustment
Adjust the drive block in the following order:
1) POWER Adjustment
2) SERVO Adjustment
3.
Precaution on the laser diode
In the POWER Adjustment, operate the drive with the disc cover
left open. During the adjustment, be sure to observe the fol-
lowing precautions:
1) Set the optical sensor disc correctly.
2) Keep the distance of more than 30 cm apart from the
camcoder.
3) Work on the LCD screen side of the camcoder (opposite
side of the drive).
Note:
Laser light of the equipment is focused by the object lens
in the optical pick-up so that the light focuses on the reflec-
tion surface of the disc.
Therefore, be sure to keep your eyes more then 30 cm apart
from the object lens when you check the emission of laser
diode.

How to Set Optical Sensor Disc
1) Before setting the optical sensor disc, remove a lug on the sensor
side of the disc.
Fig. 6-2-2
2) Push in the optical sensor disc until it clicks same as when a
disc is set, and adjust the position so that the cable from the
sensor comes just above the pickup lens, as shown below.
After positioning, fix the disc with a tape so that it does not
rotate.
