Adjustment Method
1. Discriminator (Fig.2)
Adjust T232 so thaqt leading of DIGITAL VOLT METER reads 0V
±
30mV.
Adjust T233 and TU201 so that distortion level reads minimum.
Adjust above both adjustment several times.
2. Multiplex (Fig.5)
Adjust VR251 so that Separation Ratio “Lch to Rch” and “Rch to Lch”
reads maximum and even level.
3. Signal Indicator Sensitivity (Fig.2)
Input signal 97.9kHz, 35.2dBf, 1kHz, 75kHz Deviation.
