2. CIRCUIT SYMBOLS AND SUPPLEMENTARY EXPLANATION 2-1. Precautions for Part Replacement • In the schematic diagram, parts marked (ex. • Using the parts other than those specified shall violate the regulations, and may cause troubles such as F801) are critical part to meet the safety regulations, operation failures, fire etc.
2-4. Inductor Indication Eg. 4 Unit Tolerance Fig. 3-2-4 2-5. Waveform and Voltage Measurement Eg. 5 • The waveforms for CD/DVD and RF shown in the circuit diagrams are obtained when a test disc is played back. • All voltage values except the waveforms are expressed in DC and measured by a digital voltmeter.
