For Schematic Diagrams.
Note:
•  All capacitors are in μF unless otherwise noted. (p: pF) 50 
WV or less are not indicated except for electrolytics and 
tantalums.
•  All resistors are in Ω and 1/4 W or less unless otherwise 
specifi ed.
•      f  : Internal component.
•  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.
•  Power voltages is dc 14.4V and fed with regulated dc 
power supply from ACC and BATT cords.
•  Voltages and waveforms are dc with respect to ground 
under no-signal conditions.
  no mark : TUNER (FM)
  (         ) : CD PLAY
       
*
  : Impossible to measure
•  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.
  F :

For Printed Wiring Boards.
Note:
•  X : Parts extracted from the component side.
•  Y : Parts extracted from the conductor side.
•      f  : Internal component.
• 
 : Pattern from the side which enables seeing.
  (The other layers’ patterns are not indicated.)
Caution:
Pattern face side: 
(SIDE B)
Parts face side:
(SIDE A)
Parts on the pattern face side seen 
from the pattern face are indicated.
Parts on the parts face side seen from 
the parts face are indicated.

Parts on the parts face side seen from 
the parts face are indicated.
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.
