CHARTS AND DIAGRAMS

NOTES OF SCHEMATIC DIAGRAM

Safety precautions
The Components identified by the symbol are

critical for safety. For continued safety, replace saf ety
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: KØ (1000Ø), M: MØ (1000KØ)

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).

2. Indications of control voltage

AUX : Active at high
AUX or AUX(L) : Active at low

3. Interpreting Connector indications

4) Indication on schematic diagram
Voltage Indications for REC and PB mode on the sche­matic diagram are as shown below.

Note: If the voltages are not indicated on the schematic

diagram, refer to the voltage charts.

5. Waveform measurement

1) Video circuits
REC : Colour bar signal in SP mode, normal VHS mode
PB : Alignment tape, colour bar SP mode, normal VHS

mode

2) Audio circuits
REC : 1KHz, –8 dBs sine wave signal in SP mode, normal

VHS mode

PB : REC then playback it

3) Movie Camera circuits
Measured using a correctly illuminated gray scale or colour
bar test chatrs in the E-E mode

4) Indication on schematic diagram
Waveform indications on the schematic diagram are as
