1. Clock Frequency Check

Settings :

• Test point :

TP2 (CLK)

Method :

Set to MW 1602kHz and check that the test point is
2052kHz 

±

 45Hz.

2. MW  VT  Check

Settings :

• Test point :

TP1 (VT)

Method :

Set to MW 1602kHz and check that the test point is
less than 8.0V. Then set to MW 531kHz and check
that the test point is more than 0.6V.

3. MW  Tracking Adjustment

Settings :

• Test point :

TP8 (Lch), TP9 (Rch)

• Adjustment location : L981 (1/3)

Method :

Set to MW 999kHz and adjust L981 (1/3) so that the
test point becomes maximum.

4. LW  VT  Adjustment

Settings :

• Test point :

TP1 (VT)

• Adjustment location : L942

Method :

Set to LW 144kHz and adjust L942 so that the test
point becomes 1.3V 

±

 0.05V.

Then set to LW 290kHz and check that the test point
is less than 8.0V.

5. LW  Tracking Adjustment

Settings :

• Test point :

TP8 (Lch), TP9 (Rch)

• Adjustment location :
L941 ........................... 144kHz
TC942 ......................... 290kHz

Method :

Set up TC942 to center before adjustment. The level at
144kHz is adjusted to MAX by L941. Then the level
at 290kHz is adjusted to MAX by TC942.

6. AM  IF  Adjustment

Settings :

• Test point :

TP8 (Lch), TP9 (Rch)

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

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.

8. FM  Tracking Check

Settings :

• Test point :

TP8 (Lch), TP9 (Rch)

Method :

Set to FM 98.0MHz and check that the test point is
less than 13dB

µ

V.

Settings :

• Test point :

TP3, TP4 (DC balance)

• Adjustment location : L771
• Input level :

60dB

µ

V

Method :

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

±

 0.04V. Then

check the distortion is less than 1.3%.

10. Output Level Check

<MW>
Settings :

• Test point :

TP8 (Lch), TP9 (Rch)

• Input level :

74dB
