...European FM ADJUSTMENT Festival 60/80 (TUNER UNIT)CONTINUED
Adjustment Method1. Discriminator (Fig.2)
Adjust T232 so thaqt leading of DIGITAL VOLT METER reads 0V30mV.
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.
Adjust VR231 so that Signal (TUN.) Indicator just barely turns on.
Input signal 97.9kHz, 34.2dBf, 1kHz, 75kHz Deviation.
Confirm Signal (TUN.) Indicator turns off.
