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 30 cm away from the pickup lens when the diode is turned on.
IMPORTANT SAFETY PRECAUTIONS Product Safety Notice Also check areas surrounding repaired locations. J. Be careful that foreign objects (screws, solder Some electrical and mechanical parts have special droplets, etc.) do not remain inside the set. safety-related characteristics which are often not K.

Safety Check after Servicing Examine the area surrounding the repaired location for damage or deterioration. Observe that screws, parts, and wires have been returned to their original positions. Afterwards, do the following tests and confirm the specified values to verify compliance with safety standards. 1.
