DIAGRAMS
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

/
4
W or less unless otherwise
specified.
•%: indicates tolerance.
• C : panel designation.
• A : B+ Line.
• Power voltage are dc 3.7 V and fed with regulated dc
power supply from battery terminal.
•Voltages are dc with respect to ground under tolerances.
no mark : STANDBY
(): AC ADAPTOR IN
•Voltages are taken with a VOM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal produc-
tion tolerances.
• Signal path.
F : AUDIO
NOTE FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS.
Caution:
Parts face side: Parts on the parts face side seen from
(Side A) the parts face are indicated.
Pattern face side: Parts on the pattern face side seen from
(Side B) the pattern face are indicated.
For printed wiring boards.
Note:
• X : parts extracted from the component side.
• Y : parts extracted from the conductor side.
•
: Pattern from the side which enables seeing.
(The other layers' patterns are not indicated.)
• IC101 (CXN1450-2ABL) on MAIN board cannot be replaced
individually.
Replace it with “MAIN BOARD, COMPLETE”.
• The voltage of IC101 cannot be measured.
• MAIN board is four-layer pritnted board.However, the patterns of
layer 2 and 3 have not been included in this diagrams.
