#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:

fL = 1/(1.359XR1XC1)(Hz)

fhi = 1/(1.518XR2XC2)(Hz)

fh2 = 1.214XfHI (Hz)

#4.

VTR and ITR the conditions applied to trigger input to start oscillation for VSUS ≤ VCC≤ V SI.

#5.

Trigger current must be limited to this value externally.

#6.

VDIS and IDIS are the conditions applied to trigger input to inhibit oscillation for VSI≤ V CC.
