[Three Wake-up Programs] The LED alarm clock has three wake-up programs: 1-5 (Monday to Friday), 1-7 (every day), and 6-7 (weekend mode). You can set the program for weekdays and weekends, allowing you to sleep longer on weekends. The default time format is 24-hour. To switch to 12-hour format, press the \"TIME SET\" button.

[USB or Battery Powered] The alarm clock is powered by a USB cable or 3 AAA batteries (not included, must be purchased separately). After the batteries are installed, the set alarm will sound even if the power is disconnected, and the battery will remember all \"Wake-up\" settings. When the battery is low, the screen will display a low battery icon to remind you to change the battery as soon as possible.

After changing the battery, the low battery icon will disappear.

[2 Alarms with Snooze] The teen alarm clock can set two alarms, each with its own independent switch, making it convenient for you and your family to have different schedules, and allowing you to take a five-minute nap. In addition, when the alarm sounds, the volume gradually increases, allowing you to wake up comfortably from your sleep.

[4-Level Adjustable Brightness] The digital bedside alarm clock can best meet the brightness needs of different people. The lowest brightness completely turns off the screen and does not disturb your sleep. NOTE: The screen brightness only lasts 10 seconds when powered by battery. If you want the screen to remain constantly lit, it is recommended to use a USB power supply.
