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 
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. Voltage indications for PLAY and REC mode on the schematics are as shown below:

5. How to read converged lines
