Setting up the astro planetarium
Open the battery compartment cover (12) on the
underside of the planetarium sphere (1) (Fig. 3).

Fig. 3
Loosen the screw on the battery holder (13) with
a screwdriver (you've surely got one at home).
Now lay the 3 batteries (15) into the battery com-
partment (14) as shown in figure 3.
IMPORTANT: Be sure to place the batteries in so
that their positive and negative poles are in the
right direction. The little imprints (+/-) in the bat-
tery compartment will tell you which direction is
right.
After you've installed the batteries (15), put the
battery holder (13) back on and screw it in.
Finally, you must only set the battery compart-
ment cover (12) on again.
Now place the pedestal for the planetarium
sphere (9) on a level and stable surface (e.g. on a
table) and lay the planetarium sphere (1) in. The
objective lens (7) must be parallel to the projec-
tion surface (wall or ceiling) (Fig. 4).

1.8 to
2 m
IMPORTANT: The distance between the objective
lens and the wall or ceiling should be at least 1.8
to 2 m.
NOTE: Most ceilings are approx. 2,5 m in height.
If required, use a tape measure to help you to set
the required projection distance.
Finally, turn the planetarium sphere (1) in such
a way so that the side directly across from the
slide plate holder (7) is pointing north (Fig. 4).
