Notice:
1, Numerals are big and bold, so such LED clocks are very bright. If you mind its brightness, there are 2 options: simply press "V/S" to set the display to be sound-activated OR adjust its brightness.
2, Due to big and bold LED numerals, this clock eats batteries badly (about one week if display stays on all the time; one month on display sound-activated mode). So we strongly suggest that you use charger to supply power.
3, This clock is featured with many functions, but all controlled by only 4 buttons. So the setting's a bit complicated. If you have concerns with settings, please don't hesitate to contact seller. We could help you with all the settings. If you don't want to take time to read through instruction or contact seller for help, we're sorry this clock is not suitable for your use.
