LIST OF CAUTION, NOTES, AND SYMBOLS USED IN THE SCHEMATIC DIAGRAMS ON THE FOLLOWING PAGES: 1. CAUTION:
F A V
FOR CONTINUED PROTECTION AGAINST FIRE HAZARD, REPLACE ONLY WITH THE SAME TYPE FUSE. ATTENTION: POUR UNE PROTECTION CONTINUE LES RISQES D'INCELE N'UTILISER QUE DES FUSIBLE DE MEMO TYPE. RISK OF FIRE-REPLACE FUSE AS MARKED.
This symbol means fast operating fuse. Ce symbole represente un fusible a fusion rapide.
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 defective before you connect the AC plug to the AC power supply. Otherwise it may cause some components in the power supply circuit to fail. 3. Note: (1) Do not use the part number shown on the drawings for ordering. The correct part number is shown in the parts list, and may be slightly different or amended since the drawings were prepared. (2) To maintain original function and reliability of repaired units, use only original replacement parts which are listed with their part numbers in the parts list section of the service manual. 4. Mode: SP/REC 5. Voltage indications for PLAY and REC modes on the schematics are as shown below:
< DVD Section >
1 5.0 2 3 5.0 (2.5) The same voltage for both PLAY & STOP modes Indicates that the voltage is not consistent here. The same voltage for both PLAY, REC & DVD modes PLAY mode STOP mode
