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 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
specified.
• f : internal component.
• C : panel designation.
Note: The components identified by mark 0 or dotted
line with mark 0 are critical for safety.
Replace only with part number specified.
New part of EEP ROM (IC103, IC706) on the DMB12 board
cannot be used. Therefore, if the mounted DMB12 board (A-
1166-695-A, A-1166-728-A) is replaced, exchange new EEP
ROM (IC103, IC706) with that used before the replacement.
• A : B+ Line.
• Voltages and waveforms are dc with respect to ground un-
der no-signal (detuned) conditions.
• Voltages and waveforms are dc with respect to ground in
service mode.
• Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal production
tolerances.
no mark : DVD STOP
: Impossible to measure
*
• Voltages are taken with VOM (Input impedance 10 MΩ).
• Circled numbers refer to waveforms.
