Page 3: Laser Beam Safety Precautions
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.
Page 4: Important Safeguards And Precautions
IMPORTANT SAFEGUARDS AND PRECAUTIONS 1. IMPORTANT SERVICE NOTES BEFORE RETURNING THE DVD VIDEO PLAYER Reverse the AC plug on the set and repeat AC voltage measurements for each exposed part. Any reading of Before returning the DVD video player to the user, 1.4V rms (this corresponds to 0.7mA rms AC.) or more is excessive and indicates a potential shock hazard perform the following safety checks.
Page 5: Standard Notes For Servicing
STANDARD NOTES FOR SERVICING Circuit Board Indications Using lead-free wire solder a. The output pin of the 3 pin Regulator ICs is indicated When fixing the PWB soldered with the lead-free solder, as shown. apply lead-free wire solder. Repairing with conventional lead wire solder may cause damage or accident due to cracks.
Page 6 Soldering Iron Fig. S-1-3 (2) Lift each lead of the flat pack-IC upward one by one, using a sharp pin or wire to which solder will not adhere (iron wire). When heating the pins, use a fine Fig. S-1-1 tip soldering iron or a hot air desoldering machine.
Page 7 (4) Bottom of the flat pack-IC is fixed with glue to the 2. Installation CBA; when removing entire flat pack-IC, first apply (1) Using desoldering braid, remove the solder from the soldering iron to center of the flat pack-IC and heat foil of each pin of the flat pack-IC on the CBA so you up.
