CHARTS AND DIAGRAMS
NOTES OF SCHEMATIC DIAGRAM
Safety precautions The Components indentified by the symbol are
critical for safety. For continued safety, replace safety critical components only with manufacturer's recom­mended parts.
1. Units of components on the schematic diagram
Unless otherwise specified.
1) All resistance values are in ohm. 1/6 W, 1/8 W (refer to parts list). Chip resistors are 1/16 W.
K: KΩ(1000Ω), M: M (1000K)
2) All capacitance values are in µF, (P: PF).
3) All inductance values are in µH, (m: mH).
4) All diodes are 1SS133, MA165 or 1N4148M (refer to parts list).
Note: The Parts Number, value and rated voltage etc. in the Schematic Diagram are for references only. When replacing the parts, refer to the Parts List.
2. Indications of control voltage
AUX : Active at high.
AUX or AUX(L) : Active at low.
!
4. Voltage measurement
1) Regulator (DC/DC CONV) circuits REC : Colour bar signal. PB : Alignment tape (Colour bar). — : Unmeasurable or unnecessary to measure.
2) Indication on schematic diagram Voltage indications for REC and PB mode on the sche­matic diagram are as shown below.
REC mode

(5.0)
PB mode
1.8
PB and REC modes (Voltage of PB and REC modes are the same)
Note: If the voltages are not indicated on the schematic
diagram, refer to the voltage charts.
5. Signal path Symbols
The arrows indicate the signal path as follows.
NOTE : The arrow is DVC unique object.
Playback signal path
Playback and recording signal path
CIRCUIT BOARD NOTES
1. Foil and Component sides
1) Foil side (B side) : Parts on the foil side seen from foil face (pattern face) are indicated.
2) Component side (A side) : Parts on the component side seen from component face (parts face) indicated.
rts location are indicated by guide scale on the circuit board.
2. Parts location guides
Parts location are indicated by guide scale on the circuit board.
