LED alarm clock: The projector clock has a snooze function and is equipped with an LED display whose brightness can be adjusted in 6 different levels. Rotatable projector: The time can be projected onto the bedroom ceiling, for example. You can set where you want the projection thanks to the 180-degree adjustment. Many functions: The alarm clock also has an FM radio with timer function and it indicates temperature and humidity. The mirror surface is not only a nice design idea but also allows you to actually use the clock radio as a mirror. Note: The clock must be connected to a power outlet for full functionality. The battery (CR2032 button cell battery) is only for the clock to continue showing the time, e.g. in the event of a power outage, but is not sufficient for the clock's other functions.
