Bresser ASTRO PLANETARIUM Operating Instructions Manual page 21

Problem
The planetarium is not pro-
jecting the desired portion of
the sky
The planetarium is only
projecting a bright circle of
light.
The projected image is not
visible even though the ma-
chine is turned on.
Possible Mistake
Perhaps the wrong slide plate is in the
machine.
You have probably adjusted the date
and time incorrectly.
You have almost certainly forgotten to
place a slide plate in the machine.
The sleep mode has probably been
activated.
Lay the slide plate 1) with the simulation of the sky into the holder 1! .
Adjust the date of the observation time span along with the correct time, as
described in the instructions.
Set one of the two slide plates 1) into the slide plate holder 1! .
Turn off the machine with the On/Off switch C and after about 10 seconds,
turn it back on. You can adjust the sleep mode as described in the instruc-
tions.
