The laser diode in the optical pick-up block may suffer electrostatic  
break-down because of the potential difference generated by the  
charged electrostatic load, etc. on clothing and the human body.  
During repair, pay attention to electrostatic break-down and also  
use the procedure in the printed matter which is included in the  
repair parts.  
The flexible board is easily damaged and should be handled with  
care.

NOTES ON LASER DIODE EMISSION CHECK  
The laser beam on this model is concentrated so as to be focused on  
the disc reflective surface by the objective lens in the optical pick-  
up block. Therefore, when checking the laser diode emission,  
observe from more than 30 cm away from the objective lens.  
Laser component in this product is capable  
of emitting radiation exceeding the limit for  
Class 1.  
This appliance is classified as a CLASS 1 LASER product. The  
CLASS 1 LASER PRODUCT MARKING is located on the rear  
exterior.

Flexible Circuit Board Repairing  
Keep the temperature of soldering iron around 270˚C  
during repairing.  
Do not touch the soldering iron on the same conductor of the  
circuit board (within 3 times).  
Be careful not to apply force on the conductor when soldering  
or unsoldering.
