the adjustment accuracy will be lower.

6-2-4 Connections for Adjustment

Connect the DVD video camera/recorder, jigs and test equipment as shown in the Fig. 6-2-4.
Caution
It is very dangerous to perform any work with the DVD video camera/recorder disassembled, since the
DVD video camera/recorder has a laser-emitting block and high-voltage circuits: Do not remove any
parts other than the adjustment cover.
(1) Setting of light box
1) Use the same light box as when the reference data was created: Its color temperature and
illuminance are strictly controlled and free from flickering. If the setting of color box is not
appropriate, the adjustment program may not operate normally.
