The following is a simple adjustment method. 5. Connect oscilloscope to RF/ Servo board TP (TE).
6. Adjust RV101 so that the waveform is as shown in
~ Simple Adjustment —
the figure below. (tracking gain adjustment)
Note: Since exact adjustment cannot be performed, remem-
ber the positions of the controls before performing the
adjustment. If the positions after the simple adjust-
ment are only a little different, return the controls to
the original position.
