Set the input level so that the oscilloscope waveform level becomes approx 3 V. Adjust RV401 (L-CH) and RV402 (R-CH) so that the two waveform levels on the oscilloscope become equal and their phases are reversed. Adjusting Point L-CH Pin 2 (CH1) and Pin 3 (CH2) of CN203 R-CH Pin 2 (CH1) and Pin 3 (CH2) of CN203 Adjusting Value: Waveform of Pin 2 (CH1) SW L board SW P board Adjusting Value RV401 LED B board VOL board 3. Measure the voltage of both terminals of R221 (L-CH) and R222 (R-CH) of the MAIN board, and check that the voltage is within 2 mV. (Offset voltage check) Measuring Point L-CH R-CH Both terminals of R221 Both terminals of R222 Specified Value Within 2 mV Within 2 mV RV401 THIS NOTE IS COMMON FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS.
