1. VT Adjustment
Settings:
Frequency select switch: 88.7 MHz
Test Point: TP1 (Collector of Q13)
Adjustment Location: L2
Method:
Locate the solder position of the DC voltage (VT) should be
6.0 ~ 7.0 V.
2. Sound Level Adjustment
Settings:
Adjustment Location: VR11
Method:
As described in instruction book, by turning VR11 clockwise or
counter clock wise the sound level is increased or decreased.
The factory adjusted level is set to same level under following
condition.
Radio level: 1 kHz, 75 kHz Dev
CDC level: 0 dB disc Play.
