on the ceiling or wall (Fig. 2).
7. Adjust the Focus dial (9) until the projected star field is in focus (Fig. 1). The optimal projection dis-

Using the star motion function
1. Press the Rotate left button (4) to rotate the night sky anticlockwise, which is the motion of the stars
in the Northern Hemisphere. Press the button again to increase the rotation speed. Five selectable
speeds are available. Each button push will select the next higher speed. The Rotate left button (4) will
blink according to the speed. Press the "On/Stop/Off" button to stop.
2. Similarly, press the Rotate right button (3) to rotate the stars clockwise, which is the motion of the
stars in the Southern Hemisphere. Five selectable speeds are available.
Using the falling star function
When the night sky is rotating, press the Falling star button (6) to enable the falling star function.
A falling star will appear in the night sky at regular intervals. It will appear more frequently if the rotating
speed is set higher. Press the same button again to disable the falling star function.

Press the Sleep timer button (2) to enable the sleep timer. The corresponding LED indicator will show the
currently selected timer (30 or 60 minutes). To disable the sleep timer, press the timer button until both
timer indicator lights are off. However, the projector will still turn off automatically in 2 hours to save
battery life.
Powering off
