When the tape starts running smooth, this adjustment is not necessary. this adjustment following the procedure below. 1) Solder only medium resistor pattern (B) of the MOTOR AND GOVERNOR MATCHING ADJ. Resistor group. 2) Set the tape speed (using speed adjustment SFR). 3) Restrict the motor rotation by hand (or turn PAUSE ON). 4) Remove your hand and listen to the beginning of the tape-run. 5) When the rise of tape running is smooth, no more adjustment is necessary. If wow continues for 1 to 2 seconds at the rise time, Reduce the combined resistance according to procedure 6 and check that the tape starts running smooth. 6) Solder the resistor pattern according to the table below. 7) Finally recheck the tape speed. Caution : Cool the patterns down to normal temperature after soldering. If the pattern remains heated, the governor circuit does not operate normally.
