WARNING!
Never use a Meade® LX90 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 dam- age has occurred until it is too late. Do not point the telescope at or near the Sun. Do not look through the telescope or SmartFinder as it is moving. Children should always have adult supervision while observ- ing.
CAUTION: Use care to install batteries in the orientation indicated by illustration in the bat- tery 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
