Abstract

PURPOSE: To avoid the user from being failed to hear for the time up casting, by setting an arbitrary time through the use of a plurality of switches and performing alarm casting in response to the set time.

Further, when the switch 20 is operated, the set signal is fed to the counter 3 and the digit of 1/10 second is set to an arbitrary time. Next, when the switch 21 is ON, the register 26 is oeprative, and the counter 4 is set to an arbitrary time for the digit of second with the operation of the switch 20. Similarly, minute counter 5 and hour counter 6 are set. Further, at the set of one hour, FF33 is set after one hour, the counter 39 is reset, 4kHz signal is outputted for 10 seconds.
