LASER OF CLASS 1.
SERVICING OPERATION OF THE APPARATUS
SHOULD BE DONE BY A SPECIALLY
INSTRUCTED PERSON.
LASER DIODE CHARACTERISTICS
MAXIMUM OUTPUT POWER: 7 mw
WAVELENGTH: 650 nm (DVD) , 780 nm (CD-ROM)
1. The ON/OFF(ON:low level,OFF:high level) status of the
CLAMP signals for detcting the loading state are detected
by the drive CPUs, and the design prevents laser diode
oscillation when the CLAMP signal turns OFF.
In normal operation, if no disc is clamped, the laser diode
oscillation is disabled.
However, the interlock does not always operate in the test
mode. *
2. When the cover is opened, close viewing of the objective
lens with the naked eye will cause exposure to a Class 1
laser beam.
Additional Laser Caution
* Refer to page 32.

5. PCB PARTS LIST
Parts marked by "NSP" are generally unavailable because they are not in our Master Spare Parts List.
The mark found on some component parts indicates the importance of the safety factor of the part.
Therefore, when replacing, be sure to use parts of identical designation.
When ordering resistors, first convert resistance values into code form as shown in the following examples.
Ex.1 When there are 2 effective digits (any digit apart from 0), such as 560 ohm and 47k ohm (tolerance is shown by J=5%,
and K=10%).
Ex.2 When there are 3 effective digits (such as in high precision metal film resistors).

6.2 METHOD OF INSPECTING ADJUSTMENT
• When main substrate Assy and traverse mechanism Assy are exchanged, it is necessary to write in the register in main
substrate Assy for the reading performance optimization of DVD .
The self adjustment and writing can be done from SCSI by using DOS-V personal computer and undermentioned check
program.
Check program
D7563_ DK.DAT (data file of spec for inspection)
D7563_ DK.EXE (EXE file which executes self adjustment and inspection)
Procedure
1. Main substrate Assy or traverse mechanism Assy
2. Version up and the serial number of ROM are written if there is a necessity.
3. Above-mentioned check program (D7563_DK.EXE ) is used and writing of the performance check and the DVD-ROM
adjustment value (self adjustment). (ID SW is first set as [ 5 ])
The starting method of an inspection program.
DOS mode: D7563_DK.EXE /L Return.( : space)
The content of the adjustment and the inspection is as follows.
No.
