2. DIAGRAMS
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.
C

EA
: Saudi Arabia model
MX
: Mexican model
Note: When the complete MAIN board is replaced, the desti-
nation setting is necessary. Refer to "NOTE THE MAIN
BOARD OR SYSTEM CONTROLLER (IC501) RE-
PLACING" on page 4 on original service manual.

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.
• A : B+ Line.
• Power voltages is dc 14.4V and fed with regulated dc
power supply from ACC and BATT cords.
• Voltages are dc with respect to ground under no-signal
(detuned) conditions.
no mark : TUNER (FM)
<
> : CD PLAY
• Voltages are taken with VOM (Input impedance 10 M).
Voltage variations may be noted due to normal production
tolerances.
• Signal path.
