SAFETY INFORMATION
LABEL CHECK
WARNING!
The laser component is capable of emitting radiation exceeding
the limit for CLASS 1. A specially instructed person should do
servicing operation of the apparatus.
Laser Pickup specifications and
Laser characteristics
For CD
Wave length : 785 nm
Operating output :
Read mode : 1.07 mW (CW), Class1
Maximum output : Class1M
For DVD
Wave length : 660 nm
Operating output :
Read mode : 1.08 mW, Class1
Write mode : 21.89 mW (Pulse), Class1M
Maximum output : Class2M
CLAMP signals for detecting 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
"LD Degration Judgment of ATA/ATAPI DEBUG OSD" and
"ADJUSTMENT"*.
2. When the cover is opened, close viewing of the objective
lens with the naked eye will cause exposure to a Class 3A
laser beam.
* Refer to Pages 49 and 79.

Please replace the wiring and cables to the original state after repairs.
In addition, be sure that there are no pinched wires, etc.
7 Make sure screws and soldering scraps do not remain inside the product.
Please check that neither solder debris nor screws remain inside the product.
8 There should be no semi-broken wires, scratches, melting, etc.on the coating of the power cord.
Damaged power cords may lead to fire accidents, so please be sure that there are no damages.
If you find a damaged power cord, please exchange it with a suitable one.
9 There should be no spark traces or similar marks on the power plug.
When spark traces or similar marks are found on the power supply plug, please check the connection and advise on secure
connections and suitable usage. Please exchange the power cord if necessary.
a Safe environment should be secured during servicing.
When you perform repairs, please pay attention to static electricity, furniture, household articles, etc. in order to prevent injuries.
Please pay attention to your surroundings and repair safely.
2. Adjustments
To keep the original performance of the products, optimum adjustments and confirmation of characteristics within specification.
Adjustments should be performed in accordance with the procedures/instructions described in this manual.
4. Cleaning
For parts that require cleaning, such as optical pickups, tape deck heads, lenses and mirrors used in projection monitors, proper
cleaning should be performed to restore their performances.
3. Lubricants, Glues, and Replacement parts
Use grease and adhesives that are equal to the specified substance.
Make sure the proper amount is applied.
5. Shipping mode and Shipping screws
To protect products from damages or failures during transit, the shipping mode should be set or the shipping screws should be
