LARGE DISPLAY & VERSATILE: Experience ultimate clarity with our digital alarm clock's large LED display (3.34" x 3.22" x 1.29"). Enjoy the alarm clock's 7 multi-function modes, including clock, temperature, date, night mode, snooze, date, day of the week, and alarm modes. The intuitive setting button on the top ensures easy setup, while the flashing "column" 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 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 lighting up at night. NOTE: The LED alarm clock will be on when you use 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 measurements. WEEKLY & SNOOP MODES: Start your day right with 3 alarm modes to suit your schedule: Monday-Friday, Monday-Saturday or Monday-Sunday. Easily adjust your alarm settings by long-pressing the clock's "Alarm" button and using the "Up" and "Down" buttons for fine adjustments. The digital alarm clock emits a gentle beep until it goes silent. Enjoy extra sleep with the snooze function of the travel alarm clock; simply press the snooze button when the alarm sounds for a 5-minute snooze. USB/Battery Powered: This LED clock has 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 illumination is not guaranteed when powered by batteries. Choose USB charging for uninterrupted visibility of the alarm screen.
