WARNING!
Never use a Meade
®
ETX
®
Astro Telescope
to 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 damage 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 telescope or its viewfinder as it is
moving.
Children should always have adult
supervision while observing.
Caution: Use care to install batteries in the
orientation indicated by illustration in the
battery slots of the battery compartment.
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.
