CAUTION FOR SAFETY IN PERFORMING REPAIR 1-1 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.
1-2 IMPORTANT SAFETY PRECAUTIONS 1-2-1 Product Safety Notice I. 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 evi- K.
1-2-3 Safety Check after Servicing Examine the area surrounding the repaired location for damage or deterioration. Observe that screws, parts, Chassis or Secondary Conductor and wires have been returned to their original posi- tions. Afterwards, do the following tests and confirm the specified values to verify compliance with safety Primary Circuit Terminals standards.
