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 K. Crimp type wire connector The power transformer uses crimp type connectors Some electrical and mechanical parts have special which connect the power cord and the primary side safety-related characteristics which are often not evi- of the transformer.
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 their original positions. Afterwards, do the following tests and con- Primary Circuit firm the specified values to verify compliance with safety standards.

Instructions for Handling Semi-conductors Electrostatic breakdown of the semi-conductors may occur due to a potential difference caused by electro- static charge during unpacking or repair work. 1. 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.
PREPARATION FOR SERVICING How to Enter the Service Mode About Optical Sensors Caution: An optical sensor system is used for the Tape Start and End Sensors on this equipment. Carefully read and follow the instructions below. Otherwise the unit may operate erratically. What to do for preparation Insert a tape into the Deck Mechanism Assembly and press the PLAY button.

HOW TO EJECT MANUALLY 1. Remove the Top Case, Front Assembly and Top Bracket. 2. Remove four Screws (S-3) in Fig. D3. Do not disconnect connectors. 3. While lifting up the DVD Mechanism, rotate the roulette in the direction of the arrow as shown below.
Purpose: To determine the Head Switching position during When the “0: FUNC SET” value is not “038D” playback. (DPVR-7630D) or “038F” (DCVR-7830D) or “038C” (DBVR-7730D): Symptom of Misadjustment: 1. To enter the initial function setting mode, press [0] May cause Head Switching noise or vertical jitter button on the remote control.
HOW TO INITIALIZE THE DVD PLAYER & VCR To put the program back at the factory-default, initialize the DVD player & VCR as the following procedure. < DVD Section > 1. Press [DVD], [1], [2], [3], [4], and [DISPLAY] buttons on the remote control unit in that order. Fig.

SCHEMATIC DIAGRAMS / CBA’S AND TEST POINTS Standard Notes WARNING Many electrical and mechanical parts in this chassis have special characteristics. These characteristics often pass unnoticed and the protection afforded by them cannot necessarily be obtained by using replacement components rated for higher voltage, wattage, etc.

LIST OF CAUTION, NOTES, AND SYMBOLS USED IN THE SCHEMATIC DIAGRAMS ON THE FOLLOWING PAGES: 1. CAUTION: FOR CONTINUED PROTECTION AGAINST FIRE HAZARD, REPLACE ONLY WITH THE SAME TYPE FUSE. 2. CAUTION: Fixed Voltage (or Auto voltage selectable) power supply circuit is used in this unit. If Main Fuse (F1001) is blown, first check to see that all components in the power supply circuit are not defec- tive before you connect the AC plug to the AC power supply.
