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.
