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
compartment (14) as shown in fi gure 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
battery compartment will tell you which direc-
tion 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
projection surface (wall or ceiling) (Fig. 4).

1.8 to
2 m
IMPORTANT: The distance between the ob-
jective 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).
