ADJUSTMENT
<RADIO SECTION>
1. AM IF Adjustment
L205 ................................................................. 450kHz
2. AM VT Check
Sett ngs : • Test po nt : TP1 (VT)
Method : Set to AM 530kHz and check that the voltage at the test
po nt s w th n 0.8V ~ 1.5V. Then set to AM 1710kHz
and check that the test po nt s less than 10.0V.
3. FM VT Check
Sett ngs : • Test po nt : TP1 (VT)
Method : Set to FM 87.5MHz and check that the voltage at the
test po nt s 2.3V ± 0.5V.
Then set to FM 108.1MHz and check that the test po nt
s less than 11.0V.
4. AM Track ng Adjustment
L203 ................................................................. 630kHz
TC201 ............................................................ 1440kHz
5. FM Track ng Adjustment
L201 .............................................................. 87.5MHz
<TAPE PLAYER SECTION>
6. Tape Speed Adjustment
Sett ngs : • Test tape : TTA–100
• Test po nt : Phones Jack (J101)
• Volume : MAX
• S-BASS : OFF
• Adjustment locat on : SFR401
Method : Play back the test tape and adjust SFR401 for
3010Hz ± 10Hz (FWD).
Then conf rm WOW s less than 0.52%.
