Waveform and Voltage Measurement
• 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.
Others
• The parts indicated with "NC" or "KETU" etc. are not used in the circuits of this model.
1-2. Precautions for Part Replacement
• In the schematic diagram, parts marked (ex. F801) are critical part to meet the safety regulations, so always use
the parts bearing specified part codes (SN) when replacing them.
• Using the parts other than those specified shall violate the regulations, and may cause troubles such as operation
failures, fire etc.
