For Schematic Diagrams.
Note:
• All capacitors are in μ F 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
speci fi 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 (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.
• Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal production
tolerances.
• Circled numbers refer to waveforms.
• Signal path.

Note 1: When the complete MAIN board is replaced, the destination
setting is necessary. Refer to “NOTE THE MAIN BOARD
OR SYSTEM CONTROLLER (IC501) REPLACING” on
page 4.
Note 2: When the complete BT board or complete MAIN board (in-
cluding BT board) is replaced, it is necessary to con
fi rm op-
eration. Refer to “BLUETOOTH FUNCTION CHECKING
METHOD USING A CELLULAR PHONE” on page 7.
