The potentiometer at Pin 2 adjusts the free running
frequency of the oscillator. It should normally be set
for about 55 Hz with no vertical signal input such that
it will lock to 60 Hz.

This pin requires a coupling of min 100 nF. The
composite sync input should consist of –VE sync
signal only with amplitude > 500 mVpp.
The source impedance of the sync signal should be
<1.0 k
.
Sync information at Pin 5 will override this pin, but
signals at Pin 4 will not.
Minimum pulse width is 2.0

These two pins are internally connected to each other,
and nothing else.
