(For printed wiring boards)
• : Uses unleaded solder.
• : Pattern from the side which enables seeing.
(The other layers’ patterns are not indicated)
• Through hole is omitted.
• There are a few cases that the part printed on diagram
isn’t mounted in this model.
• C : panel designation
(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, 1/4 W (Chip resistors : 1 /10 W) 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, be-
cause it is damaged by the heat.
• All variable and adjustable resistors have characteristic curve B,
unless otherwise noted.
• 2 : non flammable resistor
• 5 : fusible resistor
• C : panel designation
• f : internal component
• C : adjustment for repair
• G : IN/OUT direction of (+/–) B line
• U : B+ Line
• V : B– Line
• Circled numbers refer to waveforms.
•Voltages are dc between measurement point and ground.
• Readings are taken with a color-bar signals on DVD reference
disc.
• Readings are taken with a digital multimeter (DC 10MΩ).
•Voltage variations may be noted due to normal production toler-
ances.
• Abbreviation
AUS : Australian model
When indicating parts by reference number, please include
the board name.
