This is a plug-in, battery-powered device. 1. LED electronic clocks all need to be plugged in to stay on constantly. Batteries cannot keep them on constantly. It is recommended to use the constant light when plugged in. When the battery is installed, the screen cannot be constantly lit (the voice-controlled screen lights up for 15 seconds and then turns off, remembering the time). 2. Use carbon batteries. Do not use alkaline batteries. Excessive charge will burn out the power supply (incomplete display of the "break" character), which will shorten the lifespan of the electronic clock
