#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. V
#5. Trigger current must be limited to this value externally.
