1. Clock Frequency Check

Settings :

• Test point :

TP2 (CLK)

Method :

Set to AM 1710kHz and check that the test
point is 2160kHz

45Hz.

2. AM VT Check

Settings :

• Test point :

TP1 (VT)

Method :

Set to AM 1710kHz and check that the test
point is less than 8.5V. Then set to AM
530kHz and check that the test point is more
than 0.6V.

3. AM Tracking Adjustment

Settings :

• Test point :

TP8 (Lch), TP9 (Rch)

• Adjustment location : L981 (1/3)

Method :

Set to AM 1000kHz and adjust L981 (1/3) so
that the test point becomes maximum.

4. AM IF Adjustment

Settings :

• Test point :

TP8 (Lch), TP9 (Rch)

• Adjustment location :
L772 ........................... 450kHz

5. FM VT Check

Settings :

• Test point :

TP1 (VT)

Method :

Set to FM 108.0MHz and check that the test
point is less than 8.0V. Then set to FM
87.5MHz and check that the test point is more
than 0.5V.

6. FM Tracking Check

Settings :

• Test point :

TP8 (Lch), TP9 (Rch)

Method :

point is less than 9dB

7. DC Balance / Mono Distortion Adjustment

Settings :

• Test point :

TP3,TP4 (DC balance)

• Adjustment location : L771
• Input level :

60dB

Method :

Set to FM 98.0MHz and adjust L771 so that
the voltage between TP3 and TP4 becomes
0V

0.04V.

Next, check that the distortion is less than
1.3%.

8. Output Level Check

<AM>
Settings :

• Test point :

TP8 (Lch), TP9 (Rch)
