PRACTICAL SERVICE FIGURE
< TUNER SECTION >
1. FM VT Adjustment Settings : � Test point : TP2(VT) � Adjustment location : L006 Method : Set to FM 108.0MHz and adjust L006 so that the test point voltage becomes 6.0V ± 0.05V. 2. MW VT Adjustment Settings : � Test point : TP2(VT) � Adjustment location : L004 Method : Set to MW 1000kHz (U), and adjust L004 so that the test point voltage becomes 3.75V ± 0.05V. 3. FM Tracking Adjustment L005.........................................................................98.0MHz 4. MW Tracking Adjustment L003...........................................................................600kHz TC001.......................................................................1400kHz 5. AM IF Adjustment Settings : � Test point : TP1(DET) � Adjustment location : L007 Method : Adjust L007 so that the output level at 1400kHz becomes maximum.
