THIS NOTE IS COMMON FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS.
(In addition to this, the necessary note is printed in each block.)
For Printed Wiring Boards.
Note:
• X : Parts extracted from the component side.
• Y : Parts extracted from the conductor side.
• : Internal component.
f
• : Pattern from the side which enables seeing.
(The other layers' patterns are not indicated.)
Caution:
Pattern face side: Parts on the pattern face side seen
(Conductor Side) from the pattern face are indicated.
Parts face side: Parts on the parts face side seen from
(Component Side) the parts face are indicated.
• Indication of transistor.

AR : Argentina model
EA : Saudi Arabia model
MX : Mexican model
RU : Russian model
Note: When the MAIN board in this unit is replaced, the destination
setting is necessary. Refer to "NOTE THE MAIN BOARD OR
SYSTEM CONTROLLER (IC501) REPLACING" (page 4).

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.
• : Internal component.
f
• C : Panel designation.
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.
• 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.
