In some application, it happens that still, search or tracking is large off the point and unordinaryh SYNC

Also recommend sensitivity adjustment of outer device change, by it error detection of unodinary SYNC will lapse.
It makes volume to low value, in other word it makes time constant of M. M. to low value. In this case synchronous
peak voltage at Pin 7 becomes lower and so makes to 2V (V
(Adjust to 2V by Pin 1 resistor attached.)
SYNC occurs. If it is not desirable, you can do in SYNC condition by using Pin 6 as control input terminal.
Connect resistor and capacitor for M. M. time constant. (Value of R, C is changed by a kind of Pin 2 SYNC Input siganal.)
Input synchronous signal (Comp SYNC, H. SYNC or V. SYNC) separated from video signal.
It outputs Pin 2 or Pin 4 signal by Pin 2 signal condition.
Input artifical synchronous signal generated by SSG (Sync. Signal Generator).
GND
Input DC voltage (H or L state) by Pin 2 signal condition.
When outer SW is turned to 1, Pin 2 input signal is forced to flow out from Pin 3.
Connect capacitor for smoothing M. M. (Value depends on Pin 2 input Signal).
Adjust Pin 1 attached volume to the level that Pin 8 voltage becomes 2V (V
