L105 .................................................................... 450kHz
2. MW Tracking Adjustment
L101 .................................................................... 630kHz
VC101 ............................................................... 1440kHz
3. MW VT Check
Settings: • Test point : TP2 (VT)
Method : Set to MW 530kHz and check that the test
point voltage is more than0.9V. Then set to
MW 1602kHz and check that the test point
voltageis 7.0V +1.0/-1.5V.
4. FM Tracking Adjustment <Except YU>
L102 ................................................................. 76.0MHz
5. FM VT Adjustment <Except YU>
Settings: • Test point : TP2 (VT)
• Adjustment Location : L103
Method : Set to FM 76.0MHz and adjust L103 so that
the test point voltage becomes 1.0V ± 0.1V.
Then set to FM 108.1MHz and check that
the test point voltage is 9.0V +1.0/-2.0V.
6. FM Tracking Adjustment <YU only>
L102 ................................................................. 59.0MHz
7. FM VT Adjustment <YU only>
Settings: • Test point : TP2 (VT)
• Adjustment Location : L103
Method : Set to FM 59.0MHz and adjust L103 so that
the test point voltage becomes 0.9V to 1.0V.
Then set to FM 108.1MHz and check that
the test point voltage is within 7.0V ~ 9.5V.
8. TV/Weather Tracking Adjustment <YU only>
L151 ............................................................. 215.75MHz
9. TV/Weather VT Adjustment <YU only>
Settings: • Test point : TP2 (VT)
• Adjustment Location : L152
Method : Set the band to TV/Weather.Tune the set to
162.4MHz and adjust L152 so that the test
point voltage becomes 0.9V to 1.0V. Then
set to 215.75MHz and check that the test
point voltage is within 7.5V ~ 10.0V.
<DECK>
10. Tape Speed Adjustment
Settings: • Test tape : TTA–100(TAPE CENTER)
• Test point : PHONES JACK (J1)
• Adjustment location : SFR51
Method : Play back the test tape and adjust SFR51 so that
the frequency becomes 3015Hz±10Hz(FWD)
and ±45Hz(REV).
11. Dolby Level Adjustment
Settings: • Test tape : TTA–200
• Test point : TP6(Rch), TP7(Lch)
• Adjustment location : SFR1(Lch),SFR2(Rch)
• Power supply : 3.0V
• Dolby function : OFF
• Direction : FWD & REV
Method : Connect a coupling capacitor (10uf/16v) between
the test point and the AC voltmeter.Check that
the test point voltage is 100mV ± 1dB.Adjust
SFR1 and SFR2 for adjusting left channel and
right channel respectively.Confirm that the
level is within the specification in REV
play-back also.
