IMPORTANT
1. Connect the negative leads of the signal source and output indicator to the chassis ground unless
otherwise specified.
2. The signal input should be kept as low as possible to avoid AGC and AFT action.
3. The standard modulation is 30?4.amplitude with 400Hz signal for AM and 22.5 KHz deviation with 400Hz
signal for FM.
TUNER ADJUSTMENTS
●Use aplastic screwdriver for adjustments.
.Adjust the intermediate frequency of MW, LW and FM to the frequency of ceramic filter.
●Set of unit.
