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:
•

• 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 (detuned) conditions.

: 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.

• The voltage and waveform of CSP (chip size package)
cannot be measured, because its lead layout is different
from that of conventional IC.
Note 2:
When the complete MAIN board is replaced, be sure
to refer to “IMPORTANT NOTE FOR REPLACING
THE MAIN BOARD OR IC801 ON THE MAIN
BOARD” on page 4, and perform it.
Note 3:
Replaced old complete DISPLAY board is destroyed
with the hammer, and dispose it.
Note 4:
When the complete DISPLAY board is replaced,
be sure to refer to “IMPORTANT NOTE FOR RE-
PLACING THE DISPLAY BOARD” on page 4, and
perform it.
Note 1:
Among the parts listed in the electrical parts list
(page 61 to 70), parts described as “Not supplied”
cannot be replaced for repairing individually.

Note 5:
Electrical parts that mounted on the KEY board can-
not be replaced for repairing individually.
When the KEY board is defective, replace the FRONT
PANEL (SV) ASSY (Ref. No. FP1) including the
KEY board with a new part.
Also, block diagram, schematic diagram and printed
wiring board of the KEY board have not described in
this service manual.
