Note on 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.
• C : panel designation.
• U : B+ Line.
• Power voltage is dc 3 V and fed with regulated dc power
supply from battery terminal.
Note on Printed Wiring Board:
• X : parts extracted from the component side.
•
®
: Through hole.
• b : Pattern of the rear side.
Caution:
Pattern face side: Parts on the pattern face side seen from
(Conductor B) the pattern face are indicated.
Parts face side: Parts on the parts face side seen from
(Component A) the parts face are indicated.
• Voltages and waveforms are dc with respect to ground
under no-signal (detuned) conditions.
• Voltages are taken with a VOM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal produc-
tion tolerances.
• Signal path.
