DVD-1920 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. Do not look directly at the laser beam.
DVD-1920 IMPORTANT SAFETY PRECAUTIONS Product Safety Notice K. Crimp type wire connector The power transformer uses crimp type connectors which connect the power cord and the primary side of the transformer. When replacing the transformer, follow these steps carefully and precisely to prevent shock hazards.
DVD-1920 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. Chassis or Secondary Conductor Primary Circuit Terminals d' d 1.

Using desoldering braid, remove the solder from all pins of the flat pack-IC. When you use solder flux which is applied to all pins of the flat pack-IC, you can remove it easily. (Fig.
DVD-1920 With Iron Wire: 2. Installation 1. Using desoldering braid, remove the solder from all pins of the flat pack-IC. When you use solder flux which is applied to all pins of the flat pack-IC, you can remove it easily. (Fig. S-1-3) 1. Using desoldering braid, remove the solder from the foil of each pin of the flat pack-IC on the CBA so you can install a replacement flat pack-IC more easily. 2. Affix the wire to a workbench or solid mounting point, as shown in Fig. S-1-5. 2.
DVD-1920 Instructions for Handling Semiconductors Electrostatic breakdown of the semi-conductors may occur due to a potential difference caused by electrostatic charge during unpacking or repair work. 1. Ground for Human Body Be sure to wear a grounding band (1 MΩ) that is properly grounded to remove any static electricity that may be charged on the body. 2.
