Alarm schedules: Unlike other alarm clocks, this model offers everyday, weekday, and weekend alarm settings. The display shows the day of the week and supports both 12-hour and 24-hour formats. The alarm volume gradually increases to gently wake you without sudden loud sounds. 4-level brightness adjustment: Choose from four brightness levels to suit your environment during morning, afternoon, or evening. At the lowest setting, the screen remains dark for undisturbed sleep and reduced power consumption. Replace batteries promptly when the low battery indicator appears. USB or battery powered: When connected to USB power, the screen stays on continuously. When running on batteries with the USB cable disconnected, the screen automatically turns off after 10 seconds and lights up again for 10 seconds when any button is pressed. Alarms and all functions remain active. Dual alarm with snooze: Equipped with two independent alarms, allowing different wake-up times for you and your family. When the alarm sounds, press the "SNOOZE/LIGHT" button to snooze for 5 minutes, or press any button on the back to turn it off. Ideal for heavy sleepers. Easy to use: This compact travel alarm clock features a simple button layout for intuitive operation.
