Proper cares in using IC
1. VCO stop method
Short pin 7 and pin 3 (VCC pin) to stop the VCO.
(Note) The maximum voltage to be applied to pin 7 must not exceed the voltage on pin 3.
2. Free-running frequency check method : Use either of the following two methods.
a) Connect pin 4 to a frequency counter through the high input impedance amplifier.
