Automatic telephone dialing apparatus with electronic evaluator

摘要

Different times can be programmed using a timer. On setting the apparatus at an automatic call state, an acoustic signal sounds at programmed times, and after three minutes sounds another, louder, acoustic signal. After a further three minutes an output is switched-on, activating the automatic telephone apparatus. The above mentioned steps can be interrupted by depressing a key on a hand radio transmitter and a relay automatically switches-off the step triggered by the timer.
