ADJUSTMENT

1. AM IF Adjustment

IFT451 ................................................................... 450 kHz

2. FM IF Adjustment

CT402 ..................................................................10.7 MHz

3. AM VT Check

Settin s :  Test point : TP3 (VT)

Method : Set to AM 531 kHz and check that the test point

is 1.2 V ± 0.3 V. Then set to AM 1602 kHz and

1check that the test point is less than 7.8 V.

4. FM VT Check

Settin s :  Test point : TP3 (VT)

Method : Set to FM 87.5 MHz and check that the test point

volta e is 3.5 V ± 0.3 V.

Then set to FM 108.0 MHz and check that the test

point volta e is less than 8.5 V.

5. AM Trackin Adjustment

L451 ...................................................................... 630 kHz

CT451 .................................................................. 1440 kHz

6. FM Trackin Adjustment

CT401 ..................................................................87.5 MHz

7. FM VCO Adjustment

Settin s :  Adjustment location : SFR451

Method : Connect a frequency counter to pin 11 & 12 of IC451.

Adjust SFR 451 such that the frequency counter

indicates 19kHz ± 100 Hz.

8. Tape Speed Adjustment

Settin s :  Test tape : TTA100

 Test point : Phones Jack (J101)

 Adjustment location : SFR201

DSL : OFF

Method : Play back the test tape and adjust SFR201 for 3015 Hz

± 10 Hz (FWD) and 3015 Hz ± 50 Hz (REV).

Then confirm WOW is less than 0.5%.

9. Dolby Level Adjustment

Settin s :  Test tape : TTA200

 Test point : TP1(LCH), TP2(RCH)

 Adjustment location : A, D (LCH)

B, C (RCH)

VOLUME : MIN "0"

 DOLBY SW(AU) : OFF

Method : Connect a couplin capacitor (10 uF / 16 V) between the

test point and AC volta e meter about. Check the test

point volta e for 32 mV ± 1.0 dB. If TP1,TP2 level is

different from the SPEC, perform this adjustment

followin the procedure below:

Out level

32mV + 1dB up

32mV + 2dB up

32mV + 2.7dB up

32mV + 1dB up

32mV + 2dB up
