LARGE DISPLAY & MULTIPURPOSE: Experience ultimate clarity with our digital alarm clock's large LED display (3.34" x 3.22" x 1.29"). Enjoy the alarm's 7 multi-function modes, including clock, temperature, date, night mode, snooze, date, weekday, and alarm modes. The intuitive top setting button ensures easy setup, while the flashing "colon" between the hour and minute adds a modern touch to your space. ADJUSTABLE BRIGHTNESS: The alarm clock has three brightness levels (bright/medium/low) to easily customize your viewing experience. In night mode, the bedside alarm clock intelligently dims to create a peaceful environment. For added convenience, simply press and hold the snooze button for more than 3 seconds to prevent the screen from glowing at night. NOTE: The LED alarm clock will stay on when using the power cord. VOICE CONTROL & POWER SAVING MODE: When the alarm clock is powered by batteries, use voice control to unlock additional features. A simple sound like clapping or tapping activates the display, while the digital clock automatically enters power saving mode after 16 seconds of inactivity, saving energy while maintaining accurate time and temperature readings. WEEKDAY & SNOOP MODES: Start your day right with 3 alarm modes that fit your schedule: Monday-Friday, Monday-Saturday, or Monday-Sunday. Easily adjust alarm settings by long pressing the clock's "Alarm" button, and use the "Up" and "Down" buttons for fine adjustments. The digital alarm emits a gentle beep until silent. Enjoy extra sleep with the travel alarm snooze feature; simply press the snooze button when the alarm sounds for a 5-minute snooze. USB/Battery Powered: This LED clock features dual power options, including a USB cable (included) and 3 AAA batteries (not included). Our alarm clock is perfect for home or travel use, but constant lighting is not guaranteed when running on batteries. Choose USB charging for uninterrupted alarm screen visibility.
