SECTION 4 CHARTS AND DIAGRAMS 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. K: KШ (1000Ш), M: MШ (1000KШ) 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 1 2 3 1 2 3 4) Indication on schematic diagram Voltage Indications for REC and PB mode on the schematic diagram are as shown below. 1 REC mode 2.5 (5.0) PB mode 1.8 2 3 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.
