4-3-4 To Adjust E/F Balance (PLAY mode)
1. Set TIME/DIV of the oscilloscope to 2mS. 2. Set Volt/DIV of the oscilloscope to 0.5V. 3. Ground the scope input and set to DC. and then set the DC range. 4. Connect the GND terminal of the oscilloscope to VR and (+) terminal to center to TP2. 5. Load and play the disc. 6. Turn NVR1704 counterclockwise to the minimum value. 7. Raise NVR1702 and adjust the waveform so that its middle comes to GND of the oscilloscope (or until the upper half of waveform becomes symmetrical to the bottom half, A=B) 8. Adjust NVR1704 (arrow) for normal sound.
4-3-1 To Adjust FOCUS BIAS(STOP mode)
1. Set Volt/Div of the oscilloscope to DC 100mV. 2. Ground the scope input and set the waveform to 0V, DC range. 3. Connect the GND terminal of the oscilloscope to VR, and (+) terminal to center of TP1. 4. Set NVR1701 to 0mV.
