Setting up the astro planetarium
Open the battery compartment cover 1@ on the
underside of the planetarium sphere b (Fig.
3).
Fig. 3
Loosen the screw on the battery holder 1# with
a screwdriver (you've surely got one at home).
Now lay the 3 batteries 1% into the battery com-
partment 1$ 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
battery compartment will tell you which direc-
tion is right.
After you've installed the batteries 1% , put the
battery holder 1# back on and screw it in.
Finally, you must only set the battery compart-
ment cover 1@ on again.
Now place the pedestal for the planetarium
sphere J on a level and stable surface (e.g.
on a table) and lay the planetarium sphere b
in. The objective lens H must be parallel to the
projection surface (wall or ceiling) (Fig. 4).

N
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 B in such
a way so that the side directly across from the
slide plate holder h is pointing north (Fig. 4).
