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.

REC mode

123

2.5

(5.0)

PB mode

1.8

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.

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.

Measurement point

6. Signal path Symbols

The arrows indicate the signal path as follows.

Playback signal path
Playback and recording signal path
Recording signal path

(including E-E signal path)
Capstan servo path
Drum servo path

(Example)

R-Y

Playback R-Y signal path

Y

Recording Y signal path

7. Indication of the parts for adjustments

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

8. Indication of the parts not mounted on the circuit board

“OPEN” is indicated by the parts not mounted on the circuit
board.

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.

2. Parts location guides

Parts location are indicated by guide scale on the circuit board.

Note:

For general information in service manual, please refer
to the Service Manual of GENERAL INFORMA TION Edi­tion 4 No. 82054D (January 1994).

4. Voltage measurement

1) Video circuits

2) Audio circuits

3) Movie Camera circuits
