Proper cares in using IC
1.
VCO stop method
Short pin 7 and pin 3 (V
CC
pin) to stop the VCO.
(Note) The maximum voltage to be applied to pin 7 must not exceed the voltage on pin 3.
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.
