LASER BEAM SAFETY PRECAUTIONS This DVD player uses a pickup that emits a laser beam. Do not look directly at the laser beam coming from the pickup or allow it to strike against your skin. The laser beam is emitted from the location shown in the figure. When checking the laser diode, be sure to keep your eyes at least 30cm away from the pickup lens when the diode is turned on.
IMPORTANT SAFETY PRECAUTIONS Prior to shipment from the factory, our products are strictly inspected for recognized product safety and electrical codes of the countries in which they are to be sold. However, in order to maintain such compliance, it is equally important to implement the following precautions when a set is being serviced.

Safety Check after Servicing Examine the area surrounding the repaired location for damage or deterioration. Observe that screws, Chassis or Secondary Conductor parts and wires have been returned to original posi- tions. Afterwards, perform the following tests and con- Primary Circuit Terminals firm the specified values in order to verify compliance with safety standards.
STANDARD NOTES FOR SERVICING Circuit Board Indications Pb (Lead) Free Solder Pb free mark will be found on PCBs which use Pb 1. The output pin of the 3 pin Regulator ICs is indi- free solder. (Refer to figure.) For PCBs with Pb free cated as shown: mark, be sure to use Pb free solder.

Instructions for Handling Semiconductors Example : Electrostatic breakdown of the semiconductors may occur due to a potential difference caused by electro- static charge during unpacking or repair work. Ground for Human Body Be sure to wear a grounding band (1MΩ) that is prop- erly grounded to remove any static electricity that may be charged on the body.
