6.2.2.5.5 AUDIO CONTROL HEAD HORIZONTAL POSITION ADJUSTMENT
TOP PREVIOUS NEXT
�
Purpose: To adjust the Horizontal Position of the Audio Control Head.
�
Symptom of Misadjustment: If the Horizontal Position of the Audio Control Head is not properly adjusted, a maximum envelope cannot be obtained at the Neutral Position of the Tracking Control Circuit.
1. Connect the oscilloscope to TP3002 on the Video Signal Process Section of the Main C.B.A. Use TP6205 as a trigger. 2. Place a jumper between TP6003 on the Video Signal Process Section and +5V(TP6009) on the System Control Section of the Main C.B.A. to defeat Auto Tracking. 3. Eject the tape and insert it again to access the Neutral Tracking position. 4. Play back the alignment tape and confirm that the RF envelope appears. 5. If adjustment is required, loosen the Black Screw (D) and tighten it lightly. Set the H-Position Adjustment Driver into the Hole (A). Then slowly turn the fixture either clockwise or counterclockwise so that the envelope is at maximum. 6. Before finding the center of the maximum period of the envelope, rotate the fixture back and forth slightly to confirm the limits on either side of the maximum period. 7. Push the Tracking Control Up Button (on the Remote Control) several times (count the number of times pushed) until the maximum envelope is reduced to 1/2. 8. Reset the tracking to the neutral position by ejecting the tape and reinserting it. Push the Tracking Control Down Button (on the Remote Control) several times (count the number of times pushed) until the maximum envelope is reduced to 1/2. 9. If the number of pushing is not the same, then loosen the Black Screw (D) and set the HPosition Adjustment Driver into the Hole (A) to find the center point. Then repeat the above procedure to determine the center point.
