2. FM IF Adjustment

TC202 ...............................................................10.70MHz

3. AM VT Check Settings : • Test point : TP4 (VT) Method : Set to AM 531kHz and check that the test

point is 1.3V ± 0.3V. Then set to AM 1602 kHz and check that the test point is less than 11V.

4. FM VT Adjustment Settings : • Test point : TP4 (VT) Method : Set to FM 87.5MHz and check that the test

point voltage is 3.45V ± 0.55V. Then set to FM 108.0MHz and check that the test point voltage is less than 11V.

5. AM Tracking Adjustment

L251 ....................................................................... 630kHz

TC251 ..................................................................1440kHz

6. FM Tracking Adjustment

8. Tape Speed Adjustment Settings : • Test tape : TTA–100

• Test point : Phones Jack (J101)

• Adjustment location : SFR401

• Volume : MAX

• DSL : OFF

• Tape selector : Normal

Method : Play back the test tape and adjust SFR401 for

3015 ± 10Hz (FWD) and ± 45 (REV). Then confirm WOW is less than 0.50%.

7. FM VCO Adjustment Settings : • Adjustment location : SFR251

• Test point : TP2 (VCO)

Method : Connect a frequency counter to pin 12 of

IC251. Adjust SFR251 such that the frequency counter indicates 19kHz ± 100Hz.
