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

(3)
(4)
Load an azimuth adjustment test tape (W-f-703 etc., 10 kHz)
in tape deck.
Press the PLAY button.
Use a cross-tip screwdriver to turn the screw for azimuth
adjustment so that the left and right outputs are maximized.
Press the STOP button.
b. Replacing the Head
l After replacing the head, demagnetize the head by using a
degausser.
l All wiring should be returned to the original position after work is
completed.

d. Adjusting Tape Speed
l Use a plastic screwdriver for adjustment.
(1) Inset the test tape (Ml-T-1 11 N etc., 3000 Hz).
(2) Press the PLAY button.
(3) Use a flat-tip screwdriver to turn the SVR to adjust so that the frequency
counter becomes 3000 Hz.
e. Checking the Mechanism Torques
