ADJUSTMENT
1. Tape Speed Adjustment Settings :  Test tape : TTA  100
(Tape center)  Test point : Phones Jack (J101)  Adjustment location : SFR301  Dolby : OFF  DSL : OFF  Tape selector : NORMAL(AUTO)  Volume : Non  clip
(MAX  10 dB down)
Method : Play back the test tape and adjust SFR301 so that the
frequency becomes 3015 Hz ± 10 Hz. Then confirm WOW is less than 0.50%.
2. Dolby Level Adjustment Setting :  Test tape : TTA  200
 Test point : TP1(LCH), TP2(RCH),  DSL : OFF  Tape selector : NORMAL(AUTO)  Dolby SW : OFF  Volume : M IN  Adjustment points : Soldered patterns
Procedure : Short the patterns via solder as shown in the table so
the Dolby NR level is 32 mV ± 1.0 dB. 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).
