Features: Large Display and Multifunctional:Digital alarm clock with large LED display (6.3 inches x 0.7 ~ 1 inches x 2.3 inches), you can check the time clearly even from far away. Our desktop clock has 5 modes: clock mode, date mode, temperature mode, night mode (on/off), alarm mode. The buttons on the back are very simple instructions, so it's very easy to install! The "colon" between the hours and minutes display will keep flashing Adjustable Brightness:Just press up/down to adjust 3 levels of brightness (bright/medium/low). Also, in night mode, the alarm will automatically dim between 18:00-6:00 (or you can set another time according to your needs). Just press and hold the snooze button for more than 3 seconds to turn off the display, preventing the screen from lighting up at night.

Just long press "Alarm", then use the "UP" and "Down" buttons to adjust the hour/minute/snooze time/workday mode. Also, press the "snooze" button while the alarm is off, or press any other key to cancel the alarm, to get 1~60 minutes of extra sleep. Voice Control and Power Saving Mode:When powered by battery, you can get an extra feature - Voice Control, which means you can activate the display by making some noises, like clapping your hands, tapping on the table or touching the clock. In addition, the LED alarm automatically turns off after 16 seconds of inactivity, entering power saving mode, but the system still maintains normal timing and temperature and maintains the previous settings.
