f
: Internal component.
• 2 : Nonfl ammable resistor.
• 5 : Fusible resistor.
• C : Panel designation.
THIS NOTE IS COMMON FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS.
(In addition to this, the necessary note is printed in each block.)
• A : B+ Line.
• Voltages and waveforms are dc with respect to ground
under no-signal conditions.
no mark
: POWER ON
• Voltages are taken with VOM (Input impedance 10 M).
Voltage variations may be noted due to normal production
tolerances.
• Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal production
tolerances.
• Circled numbers refer to waveforms.
• Signal path.

Note: The components identifi ed by mark 0 or
dotted line with mark 0 are critical for safety.
Replace only with part number specifi ed.
Note: Les composants identifi és par une marque
0 sont critiques pour la sécurité.
Ne les remplacer que par une piéce portant
le numéro spécifi é.
Note 1: When the complete MAIN board is replaced,
refer to “NOTE OF REPLACING THE IC1000
AND IC1002 ON THE MAIN BOARD AND
THE COMPLETE MAIN BOARD” on page 5.
Note 2: When the complete MAIN board is replaced,
spread the bond referring to“BOND FIXATION
OF ELECTRIC PARTS” on page 6.
