PAGES:
1.
CAUTION:
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 MÊME TYPE.
RISK OF FIRE-REPLACE FUSE AS MARKED.
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. Wire Connectors
(1) Prefix symbol "CN" means "connector" (can disconnect and reconnect).
(2) Prefix symbol "CL" means "wire-solder holes of the PCB" (wire is soldered directly).
5. Voltage indications for PLAY and STOP mode on the schematics are as shown below:
6. How to read converged lines
7. Test Point Information
