1. MAIN AND KEY BOARDS DISCRIMINATION

Confi rm by the part number of the MAIN and KEY boards.
– MAIN Board (Component Side) –
Former : 1-886-982-12
(BT31PW/BT3100P/BT3150U: E, Mexican, Argentina/BT3153U)
1-887-147-11
(BT3100U/BT3150U: Saudi Arabia model)
New : 1-886-982-21 or 1-886-982-22
(BT31PW/BT3100P/BT3150U: E, Mexican, Argentina/BT3153U)

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
Q These are omitted.
B E
• Abbreviation
AR : Argentina model
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.

– KEY Board (Component Side) –
Former : 1-886-920-11
New : 1-886-920-21 or 1-886-920-22
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
: Impossible to measure
*
• Voltages are taken with VOM (Input impedance 10 M).
Voltage variations may be noted due to normal production
tolerances.
• Signal path.
