【Large Display & Multi-Function】Digital alarm clock with large LED display (6.3\"x0.7~1\"x2.36\"), allowing 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. 【Adjustable Brightness】Just 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 other time periods as needed. 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 additional 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 inactivity and enter power saving mode, but the system still keeps normal timekeeping and temperature and maintains the previous settings. 【Workday Mode and Snooze】There 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. 【USB and Battery Powered】For this dual alarm clock, which comes with 1 meter/39.37 inch power cable (AC adapter not included) - very good for battery saving. And it comes with time memory function when charging with AAA batteries. (When powered by USB alone, there is no time memory function after power off).
