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:
•

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

•
C
: Panel designation.
•
A
: B+ Line.
• Voltages are dc with respect to ground under no-signal
conditions.
no mark : POWER ON

: Impossible to measure
• Voltages are taken with VOM (Input impedance 10 M
).
Voltage variations may be noted due to normal production
tolerances.
• Signal path.

Note 1:
When the complete MAIN board is replaced, refer
to “NFC CONNECTION CHECKING METHOD”
on page 4, “WIRELESS CONNECTION (LINK)
WORK OF BAR SPEAKER AND SUBWOOFER”
on page 5 and “SPREADING OF COMPOUND” on
page 7.
Note 2:
Among mounted electrical parts on each boards, only
parts that are described in the electrical parts list can
be replaced for repair.
The parts that are not described in the electrical parts
list cannot be replaced with single for repairing.
