ADJUSTMENT
<TAPE PLAYER SECTION>
1. Tape Speed Adjustment
Settings : • Test tape : TTA – 100 (Tape center)
• Test point : Phones Jack (J101)
• Adjustment location : SFR401
• Dolby SW : OFF
• Super Bass : OFF
• Direction : FWD
• Tape selector : NORM
• Volume : MAX
Method : Play back the test tape and adjust SFR401 so that
the frequency becomes 3015Hz ± 10Hz. Then
confirm WOW is less than 0.55%.
2. Dolby Level Adjustment
Setting : • Test tape : TTA – 200
• Test point : TP1(LCH), TP2(RCH),
TP3(GND)
• Direction : FWD, REV
• Tape selector : NORM
• Dolby NR : OFF
• Volume : MIN
• Solder points : Dolby adjust point 1, 2, 3
Method : Connect 10µF/16V coupling capacitors between
solder points and test equipment (connect the
positive terminals to the solder points). Short the
Dolby adjust point via solder as shown in the
table so the Dolby level becomes100mV ± 1.0dB
in both the forward and reverse directions.

TEST MODE
This model has a test mode function in the disassembled condition.
1. How to use the test mode:
• short the test land in the MAIN C.B.
• auto-stop function is not detected by micro-computer while test mode is active.
Note: Make sure that the test land is opened after the test mode is de-activated.
(Auto-stop function is not available with shorted land condition.)
2. How to disassemble the circuit board.
• removes the soldering part in the MAIN C.B (with the mark).
• removes two screws.
