NOTES OF SCHEMATIC DIAGRAM
Safety precautions
The Components identified 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.
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 (ref er to parts
Note: The Parts Number, value and rated voltage etc. in
the Schematic Diagram are for references only.
K: KΩ (1000Ω), M: MΩ (1000KΩ)
list).
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
