Activate the projection function with the projection control; adjust the projection angle by rotating or tilting the clock body to aim the projected image at the desired surface. The temperature display updates based on the built-in sensor.

Recommendations

Place the clock on a stable, level surface facing the area where you want the projection to appear.
