TAPE ADJUSTMENTS
a. Adjusting Azimuth
●Be sure to clean the heads before attempting to make any adjustment.
.Be sure both channel’s waveform are the same for the phase matching.
●Be sure both channels (1 and 2) are the same level using adual-channel oscilloscope.
.After completion of the adjustment, apply thethreadlock(TB-1401 B) to the azimuth adjustment screws to fix them securely.
