ABSTRACT:
A programmable microcomputer controlled alarm clock has a multi-key input keyboard for setting the time of day, the month and date, and the alarm times of two or more independent alarms. Each alarm may be set to generate an alarm signal at a selected time on each day of two to six consecutive days of a seven-day period, the alarm sequence being automatically repeated each following seven-day period. In the normal operational mode, time of day is displayed until a month-and-date switch, an alarm-period or doze switch, or an alarm-enabling switch is actuated to display the respective date and alarm time. After the particular switch is actuated and the appropriate time information displayed, the clock returns to display time of day within several seconds.
