(11) Pin 11 is to be connected with hor osc capacitor.
When shifting control range of frequency to upper or lower,
the value of capacitor is changed as requested.
(15) Pin 15 is control terminal of H. OUT DUTY.
Controlling the voltage at this terminal from 9V to approx.
7.5V makes possible to regulate the DUTY of H. OUT. The
controlling range is approx. 28% to 66%. DUTY of H. OUT,
when d.c. voltage of pin15 is fixed, is always kept constant
even though hor osc frequency is changed by controlling
voltage at pin8.

(12) Pin 12 is GND terminal of horizontal block.
(13) Pin 13 is a low pass filter giving band limit to hor osc
circuit.

(14) Pin 14 is Vcc terminal of horizontal block.
Since pin 14 has approx. 9V regulator inside IC, current of
approx. 60 mA is applied at this pin.

(16) Pin 16 is hor output terminal.
The output voltage is approx. 5V when the terminal is set in
high impedance. And output current becomes approx. 2mA
when the terminal is connected to ground through 100 ohm.
Internal transistor can accept current of approx. 10mA.

(17) Pin 17 is vacant terminal.
(18) Pin 18 is input terminal of FBP
Threshold voltage inside IC is approx. 1.5V. When this
voltage becomes 1.5V or more, Mono-multi which is
connected to pin20, begins operation.
