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! Adjustable BrightnessJust press UP/DOWN to adjust the three brightness levels (High/Medium/Low). In addition, the bedside clock will automatically dim during 6:00 PM-6:00 AM in night mode, or you can set another time period for your need. Just press and hold 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 & Power Saving Mode When powered by battery, you can get an extra function - voice control, which means you can activate the display by making a little 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 the normal time and temperature and maintains the previous settings. Workday Mode; SnoozeThere are 3 alarm modes to choose from when you want it to wake you up at a fixed time: Monday to Friday/Monday to Saturday/Monday to Sunday. Just long press \"ALARM\", and then use the \"UP\" and \"DOWN\" buttons to adjust the hour/minute/snooze time/workday mode. In addition, you can get 1~60 minutes of extra sleep by pressing the \"SNOOZE\" button when the alarm goes off, or press any other button to cancel the alarm.
