CHARTS AND DIAGRAMS

NOTES OF SCHEMA TIC 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.

K or k: k

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 shown below.
