Settings :  Test tape : TTA  100 (Tape center)
 Test point : Phones Jack (J101)
 Adjustment location : SFR301
 Dolby : OFF
 MSP : CLASSIC
 DSL : OFF
 Tape selector : NORMAL(AUTO)
 Volume : MAX
Method : Play back (FWD) the test tape and adjust
SFR301 so that the frequency becomes
3015Hz ± 10Hz. Then confirm WOW is
less than 0.50%.
2. Dolby Level Adjustment
Setting :  Test tape : TTA  200

 DSL : OFF
 Tape selector : NORMAL
 Dolby SW : OFF
 Volume : MIN
 Adjustment points : Soldered patterns 
Procedure : Short the patterns via solder as showen in the
table so the Dolby NR level is 24.5mV ± 1.0dB.
Adjust so the specifications are satisfied in both
the forward and reverse directions. Connect 10mF
/16V coupling capacitors between test points and
test equipment (connect the positive terminals to
the test points).
