When the tape starts running smooth, this adjustment is not necessary. If wow is conspicuous at the beginning of the tape-run, perform this adjustment following

32、the procedures below. 1) Solder resistor pattern of the MOTOR AND GOVERNOR MATCHING ADJ. resistor group. 2) Set the tape speed (using speed adjustment SFR101). 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

33、of tape running is smooth, no more adjustment is necessary. If wow continues for 1 to 2 seconds at the rise time, change 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 re-check th

34、e tape speed. Caution : Cool the patterns down to normal tempera- ture after soldering. If the pattern remains heated,the gorvernor circuit does not operate normally.
