Large Display & MultifunctionDigital alarm clock with large LED display (6.3\"x0.7~1\"x2.36\"), which allows you to check the time clearly at a glance even if it is far away from you. Our smart clock with 5 modes: clock mode, date mode, temperature mode, night mode (ON/OFF), alarm mode. The buttons on the back are very self-explanatory, so it is very easy to set! The \"column\" between the hour and minute display flashes continuously Adjustable BrightnessJust press UP/DOWN to adjust the three brightness levels (High/Medium/Low). In addition, the bedside table clock will automatically dim during 6:00 PM-6:00 AM in night mode, or you can set other time periods as needed. Just press the snooze button for more than 3 seconds to turn off the display to prevent the screen from lighting up at night and disturbing your sleep. (NOTE: If you use a cable for power supply, the clock will always be on.) Voice Control and Power Saving Mode When powered by battery, you can get an extra function - voice control, which means you can activate the display by making some sound like clapping your hands, tapping the table or touching the clock. In addition, the LED alarm clock will automatically turn off after 16 seconds of no use and enter power saving mode, but the system still keeps normal timekeeping and temperature and maintains the previous settings.
