Adjust the time (hour / minute) + alarm (hour / minute). Without alarm mode, single alarm or alarm with repetitions (infinite?). Mode 12h / 24h. And light orange color evenly distributed over the entire surface. Big numbers, very legible, even at night. In closed mode, only the button light / alarm stop is accessible. The light turns on only when pressing the button. No other light other times. So any gene night. If absent, the alarm goes off for 1 minute each time. Requires 2 LR44 button batteries style.
