4-2. PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS

THIS NOTE IS COMMON FOR WIRING BOARDS AND SCHEMATIC DIAGRAMS.
(In addition to this, the necessary note is printed in each block)
For printed wiring boards:
• : indicates a lead wire mounted on the component
side.
• : indicates a lead wire mounted on the printed side.
• a : Through hole.
• : 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
from
(Side A) the pattern face are indicated.
Parts face side: Parts on the parts face side seen from
(Side B) the parts face are indicated.
• Abbreviation
AEP : Europe Model
CND : Canadian Model
E : Latin America Model
KR : Korea Model
RUS : Russian Model
SP : Singapore Model

WAVEFORMS

ER-41, MV-49
For schematic diagrams:
• All capacitors are in µF unless otherwise noted. pF : µµF.
50V or less are not indicated except for electrolytics and
tantalums.
• All resistors are in ohms, 1/4W (Chip resistors : 1/10W)
un-less otherwise specified.
kΩ = 1000Ω, MΩ = 1000kΩ.
• Caution when replacing chip parts.
New parts must be attached after removal of chip.
Be careful not to heat the minus side of tantalum capacitor,
because it is damaged by the heat.
• All variable and adjustable resistors have characteristic
curve B, unless otherwise noted.
• : non flammable resistor.
• : fusible resistor.
• : panel designation.
• f : internal component.
• : adjustment for repair.
• Circled numbers refer to waveforms.
• Voltages are dc between measurement point.
• Readings are taken with a color-bar signal on DVD refer-
ence disc and when playing CD reference disc.
• Readings are taken with a digital multimeter (DC 10MΩ).
• Voltage variations may be noted due to normal production
tolerances.
Note:
The components identified by
mark or dotted line with mark
are critical for safety.
Replace only with part number
specified.
When indicating parts by reference
number, please include the board
name.
