The customizable projection alarm clock displays the indoor and outdoor temperature, temperature trend, and weather trend. A quick glance is all you need - the digital projection clock projects the current time and outdoor temperature onto the ceiling or wall at the push of a button (battery-operated) or continuously (mains-operated). The clock, which allows for free adjustment of the display color, is always highly accurate and does not forget the switch between summer and standard time - it is controlled via radio by the DCF77 time signal transmitter. The highly adjustable projector allows for the free choice of the desired projection surface. The alarm clock features an alarm function with two alarm times and a snooze function.
