ABSTRACT:
A portable automated dialer capable of generating a predetermined sequence of tones including DTMF tones into the microphone of a telephone. The automated dialer includes a signal generator for generating a series of tone signals, a speaker electrically connected to the signal generator for transmitting the tone signals as a series of audible tones and a tone completion indicator operating in at least a first and second state such that the tone completion indicator changes from the first state to the second state after the signal generator generates a last tone signal in the series of tone signals. The indicator may be a visual, auditory, tactile or even olfactory indicator.
