How do I project the time onto the ceiling or wall, and can I switch between time and temperature?

Press the button (button 1) to switch on the projection for about 5 seconds, or use the permanent projection On/Off switch (switch 0) with the power adapter connected for continuous projection. To switch the projection between time and temperature, press and hold the ROTATION TIME/TEMP button for around 3 seconds while the projection is on. The projection arm can be swivelled 180°, and the FOCUS dial on the rear of the arm can be used to sharpen the image. (Page 20-21)
