The alarm clock is set alone, even to schedule changes. It has two possible ringing alarm clocks. And when the alarm gets going, it can be stopped and resumed after 4 minutes, etc. I had almost the same number of years ago, and it uses two batteries while the former, a single battery. And at night, if we want to look at the time, you press a button that lights up the screen but the brightness is a bit high compared to the old clock, the only flaw in this revival.
