The display has 3 different light levels, so you can choose the brightness that suits you.
The wake-up function works even if you turn off the screen.
The alarm clock can be powered by a USB cable or batteries. When running on battery power, the screen will only illuminate briefly if you press any button. With a USB cable, the screen stays illuminated the entire time.
You can select the time format – 12 or 24-hour display.
