ADJUSTMENT
< TUNER SECTION > 1. AM IF Adjustment IFT201 .................................... 450kHz 1. Tape Speed Adjustment Settings : · Test tape : TTA-100 (TAPE CENTER) · Test point : PHONES (J101) · Adjustment location : SFR101 · Super Bass : OFF · Volume : MAX Method : Play back the test tape and adjust SFR101 for 3000Hz ± 10Hz (FWD). Then confirm WOW is less than 0.50%.

2. AM Tracking Adjustment L201 ........................................ 630kHz TC201 ..................................... 1440kHz

3. FM Tracking Adjustment L202 ........................................ 76MHz

4. FM VT Adjustment Settings : · Test point : TP1 (VT) · Adjustment location : L203 * Short IC501 Pin 6 (PA0) and Pin 7 (PB3) together. Method : Set to FM 76MHz and adjust L203 so that the test point becomes 1.1V ± 0.1V. Then set to FM 108.1MHz and check that the test point is less than 7V.

2. Azimuth Adjustment Settings : · Test tape : TTA-330 · Volume : MAX · Adjustment location : Head azimuth adjustment screw Method : Play back (FWD) the test tape and adjust screw so that the 8kHz signal output is maximum.
