ADJUSTMENT
<RADIO SECTION>
1. AM IF Adjustment
L105 ....................................................................... 450kHz
2. AM VT Check
Settings: • Test point : TP2 (VT)
Method : Set to AM 530kHz and check that the test
point is more than 0.8V. Then set to AM 1710
kHz and check that the test point is less than
8.7V.
3. AM Tracking Adjustment
L101 ....................................................................... 630kHz
VC101 .................................................................. 1440kHz
4. FM VT Adjustment
Settings: • Test point : TP2 (VT)
• Adjustment location : L103
Method : Set to FM 76MHz and adjust L103 so that the
test point becomes 1.0V ± 0.1V. Then set to
FM 108.1MHz and check that the test point
is less than 8.5V.
5. FM Tracking Adjustment
L102 ....................................................................... 76MHz
<TAPE PLAYER SECTION>
6. TapeSpeedAdjustment
Settings : • Test tape : TTA–100 (TAPE CENTRE)
• Test point : Phones Jack (J1)
• Adjustment location : SFR1
• Tape/radio : TAPE
•S-BASS : OFF
• Volume: NON-CLIP(MAX -10dB )
Method : Play back the test tape and adjust SFR1 for
3000 ± 10Hz. Then confirm WOW is less than 0.50%.
7. Azimuth Adjustment
Settings : • Test tape : TTA–330/TTA–420
• Test point : Phones Jack (J1)
•S-BASS : OFF
• Tape/radio : TAPE
•Volume : MAX
• Adjustment location : Head azimuth adjustment
screw
Method : Play back the 8KHz signal of the test tape and
adjust screw so that the output becomes maximum.
