and press the on/off/ button
C
to start the projection.
You can make further adjustments to the pro-
jection angle for an optimal image on the wall
or ceiling by moving the planetarium sphere

. In fi gure 11, you can see the
possibilities for projecting onto the ceiling (a) or
the wall (b).

correct focus for image projection (Fig. 12).

IMPORTANT: The correct distance between
the objective lens and the wall or ceiling is be-
tween 1.8 and 2 m. If you have tried to focus
the image, but it still remains fuzzy, you have
probably not chosen the correct projection dis-
tance.
Press the sleep mode button
E
to set the time
(30 or 60 minutes) for activating the automatic
shut-down function. The corresponding LED
lamp will light up. At the designated time, the
device will switch itself to sleep mode (also en-
ergy saving mode). If you wish to turn off the
sleep mode, press the button
E
until the LED
lamp goes out. In order to save energy, the pro-
jection automatically shuts down after 2 hours.
When the astro planetarium is not in use, the
device should be turned off simply by pressing
the on/off/pause button
C
. Remove the batter-
ies from the device if it is out of use for a long
period (1 week or more).
Using the image rotation function
Press the button for left-sided rotation
1&
to
make the night sky projection move in an au-
tomatic, anti-clockwise direction. This corre-
spods to the natural motion sequence of the
northern hemisphere.
You can infl uence the speed of movement by
pressing the button again. In total, there are 6
different speed settings. The LED light fl ashes
according to the set speed.
Press the on/off/pause button
C
to stop the
rotation.
Similarly, image rotation can also be activated
and adjusted to the southern hemisphere. In
this case, press the button for right-sided rota-
tion
1^
. All other functions are identical to those
for left-sided rotation.
