About this product: Large screen display and multi-functionality: This digital alarm clock features a large LED display (6.3 inches x 0.7 inches to 1 inch x 2.36 inches), ensuring clear time reading even from a distance. Our desktop alarm clock offers 5 modes: clock mode, date mode, temperature mode, night mode (on/off), and alarm mode. Adjustable brightness: Simply press the up/down buttons to adjust to 3 brightness levels (high/medium/low). Additionally, in night mode, the alarm automatically dims between 6:00 PM and 6:00 AM (you can also set other time periods as needed). Simply press and hold the snooze button for more than 3 seconds to turn off the display and prevent it from lighting up while you sleep at night (Note: If using a power cord, the alarm will always remain on). Weekday snooze mode: The alarm clock offers three modes to help you wake yourself at a fixed time: Monday to Friday / Monday to Saturday / Monday to Sunday. Simply press and hold the "Alarm" button, then use the "Up" and "Down" buttons to adjust the hour/minute/snap time/weekday mode. In addition, when the alarm rings, you can press the "Sniff" button to get 1-60 minutes of extra sleep time, or press any other button to cancel the alarm. Two power supply options: This bedroom alarm clock comes with a 1.5-meter/59-inch power cord (AC adapter not included), which is very energy-efficient and has a time memory function when using AAA batteries. (When using only the Type-C data cable for power, the time memory function will be lost after a power outage). We recommend installing batteries and using the Type-C data cable for continuous power supply, so that the screen will remain lit after the alarm is powered off and the time memory function will be maintained. You can check the alarm settings at any time. Check the time anytime and save energy Note: 1. When using only battery power, pressing any button will wake the screen. 2. When using Type-C power, the screen remains on. 3. In night mode, the screen brightness will automatically adjust to 3%.
