2. HEAD AZIMUTH ADJUSTMENT
(1) Load the test tape(VTT-703, etc., 10 kHz) for azimuth
adjustment.
(2) Press the PLAY button.
(3) Use a cross-tip screwdriver to turn the screw for azimuth
adjustment so that the left and right output are maximized.
(4) Press the STOP button.
(5) After completion of the adjustment, use thread lock(TB-1401B)
to secure the azimuth-adjustment screw.
3. MOTOR SPEED ADJUSTMENT
(1) Insert the test tape(TCC-119, etc., 3,000 Hz).
(2) Press the PLAY button.
(3) Use a flat-tip screwdriver to turn the SVR(located inside the
rear of the motor) to adjust SVR so that the frequency counter
become 3,000 Hz.
4. CHECKING THE MECHANISM TORQUES AND TENSION
• Clean the head, capstan and pinch roller before making any measurement.

1. HEAD REPLACEMENT
• After replacement, demagnetize the heads by using a degausser.
• Be sure to clean the heads before attempting to make any adjustments.
• All wiring should be returned to the original position after work is completed.
TAPE DECK ADJUSTMENTS
This is a basic adjustment.
