WARNING!
®
Never use a Meade
look at the Sun! Looking at or near the Sun
will cause instant and irreversible damage to
your eye. Eye damage is often painless, so
there is no warning to the observer that dam-
age has occurred until it is too late. Do not
point the telescope or its viewfinder at or
near the Sun. Do not look through the tele-
scope or its viewfinder as it is moving.
Children should always have adult supervi-
sion while observing.
CAUTION: Use care to install batteries in
the orientation indicated by illustration in the
battery slots of the battery holder. Follow
battery manufacturer's precautions. Do not
install batteries backwards or mix new and
used batteries. Do not mix battery types. If
these precautions are not followed, batteries
may explode, catch fire, or leak. Improperly
installed batteries void your Meade warranty.
If you are anxious to use your telescope
for the first time, read the QUICK-START
GUIDE on pages 4 and 5.
