#1.

Supply initiation voltage is the value of DC supply voltage required to start the tone ringer oscillating.

#2.

Sustaining voltage is the value of DC supply voltage required to maintain the oscillation.

#3.

Oscillator frequency is determined by the following equations:

#4.

#5.

Trigger current must be limited to this value externally.
