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: MΩ (1000KΩ)

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

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.

6. Indication of the parts for adjustments

The parts for the adjustments are surrounded with the circle as shown below.

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.

Parts 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.
