THIS NOTE IS COMMON FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS.

(In addition to this, the necessary note is printed in each block.)

for schematic diagram:
•	All capacitors are in µF unless otherwise noted. pF: µµF
	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
	specified.
•	%	: indicates tolerance.		CN2
•	f	: internal component.
•	C : panel designation.

•A : B+ Line.

•Power voltage is dc 14.4V and fed with regulated dc power supply from ACC and BATT cords.

•Voltages are taken with a VOM (Input impedance 10 MΩ ). Voltage variations may be noted due to normal produc- tion tolerances.

•Waveforms are taken with a oscilloscope.

Voltage variations may be noted due to normal produc- tion tolerances.

•Circled numbers refer to waveforms.

•Signal path. F : FM f : AM

J : CD

for printed wiring boards:

•X: parts extracted from the component side.

•Y: parts extracted from the conductor side.

•x : parts mounted on the conductor side.

•a : Through hole.

• : Pattern from the side which enables seeing. (The other layer’s patterns are not indicated.)

Caution:

Pattern face side: Parts on the pattern face side seen from the

(Side B) pattern face are indicated.

Parts face side: Parts on the parts face side seen from the

(Side A) parts face are indicated.
