ADJUSTMENT
MAIN C.B
SFR301
< TAPE PLAYER SECTION >
1. Tape Speed Adjustment
Settings : * Test tape: TTA-100
* Test point: PHONES JACK
¢ Adjustment location : SFR301
Method : Play back the test tape, adjust for
3000 + 10Hz, - 5Hz at FWD and less
than 45Hz at REV.
. Dolby Level Check
Settings : * Test tape: TTA-200
¢ Test point: TP1 (L ch), TP2 (R ch),
TP3 (GND)
* DOLBY SW: OFF
¢ TAPE SELECTOR : NORM
¢ DIRECTION : FWD
¢ VOLUME: MIN “0”
Method : Connect at electrolytic capacitor (10 uwF/16V)
to measured equipment and TP1 (2),
check the voltage for 100mV + 1.5dB, — 0.5dB.
. Azimuth Adjustment
Settings : * Test tape: TTA-320
¢Test point : PHONES JACK
¢ Adjustment location: Azimuth adjustment
screw
Method : Play the 8kHz signal of the test tape and
e

~~
adjust
so
the
output
is
maximum
and
the
waveforms in the Lissajours’ figure are in
phase.
. Motor load Adjustment
Refer to the REF No. SI*88-037-OP of service technical
information.
