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:
• 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.)
Caution:
Pattern face side: Parts on the pattern face side seen
(SIDE B) from the pattern face are indicated.
Parts face side: Parts on the parts face side seen from
(SIDE A) the parts face are indicated.
• MOTHER board is multi-layer printed board. However,
the patterns of intermediate layers have not been includ-
ed in diagrams.
• Indication of transistor.

Note 1: Among mounted electrical parts on each board, only
parts that are described in the electrical parts list can
be replaced for repairing.
The parts that are not described in the electrical parts
list cannot be replaced with single for repairing.
Note 2: Among mounted parts on the MOTHER board, only
parts that are described in the electrical parts list can
be replaced for repairing.
When the parts that are not described in the electrical
parts list are defective, replace the complete mounted
board.
In this service manual, the block diagram and printed
wiring board of the MOTHER board are described
for reference.
Also, when the MOTHER board is replaced, be sure
to refer to "DESTINATION SETTING METHOD"
and "NFC OPERATION CHECKING METHOD"
on page 6.
Note 3: When the PARTY LED, SW LED, NFC and MS-476
boards are defective, replace the complete mounted
board or the whole parts including the applicable
board.
The mounted parts cannot be replaced with single for
repairing.
In this service manual, the schematic diagram and
printed wiring board of the PARTY LED, SW LED,
NFC and MS-476 boards are not described.
Also, when the NFC board is replaced, be sure to re-
fer to "NFC OPERATION CHECKING METHOD"
on page 6.
Note 4: When the SMPS board is defective, replace the com-
plete mounted board.
The mounted parts cannot be replaced with single for
repairing.
However, in this service manual, the block diagram,
schematic diagram and printed wiring board of the
SMPS board are described for reference.

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 1/4 W or less unless otherwise
specifi ed.
• 2 : Nonfl ammable resistor.
• C : Panel designation.
Note: The components identifi ed by mark 0 or dotted
line with mark 0 are critical for safety.
Replace only with part number specifi ed.
• A : B+ Line.
• Voltages are dc with respect to ground under no-signal
(detuned) conditions.
no mark : TUNER (FM)
* : Impossible to measure
• Voltages are taken with VOM (Input impedance 10 M).
Voltage variations may be noted due to normal production
tolerances.
• Signal path.
d : USB
: MIC
