ADJUSTMENT <TUNER / DECK>

< TUNER SECTION >

1. Clock Frequency Check

Settings : Test point : TP2

Method : Set to AM 1602kHz and check that the test

point is 2052kHz ± 45Hz.

2. MW VT Adjustment

Settings : Test point : TP1 (VT)

Adjustment location : L981 (3/3)

Method : Set to MW 1710kHz and adjust L981 (3/3) so

that the test point becomes 7.5V ± 0.05V. Then

check that the test point is more than 0.3V

(530kHz).

3. SW VT Adjustment

Settings : Test point : TP1 (VT)

Adjustment location : L942

Method : Set to SW 17.9MHz, 5.9MHz and adjust L942

so that the test point becomes 6.0V ± 0.05V.

Then check that the test point is more than 0.3V

(5.9MHz).

4. FM VT Check

Settings : Test point : TP1 (VT)

Method : Set to FM 87.5MHz, 108.0MHz and check that

the test point is more than 0.5V (87.5MHz) and

less than 8.0V (108.0MHz).

5. MW Tracking Adjustment

Settings : Test point : TP8(Lch), TP9(Rch)

Adjustment location :

L981 (1/3) .................................... 603kHz

TC941 .......................................... 1404kHz

Method : Set up TC941 to center before adjustment, the

level at 603kHz is adjust to maximum by L981

(1/3). Then the level at 1404kHz is adjust to

maximum by TC941.

6. SW Tracking Adjustment

Settings : Test point : TP8(Lch), TP9(Rch)

Adjustment location :

L941 .............................................. 5.9MHz

TC943 .......................................... 17.9MHz

Method : Set up TC943 to center before adjustment. The

level at 5.9MHz is adjust to maximum by L941.

Then the level at 17.9MHz is adjust to

maximum by TC943.

7. 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 9dB.

8. AM IF Adjustment

Settings : Test point : TP8(Lch), TP9(Rch)

Adjustment location :

L772 ............................................... 450kHz
