Maintenance; Important: Battery Information - My First Lab DUO SCOPE MFL-06 User Manual

To prolong the life of your batteries, turn off the power immediately when not
in use (be sure all lights are off—switch in the center position.) Dust the unit
with a soft dry cloth or soft brush. Fingerprints and debris may be removed
with a damp cloth. If glass lens require cleaning, try a cotton swab very
slightly moistened with alcohol. Dry with a clean swab or lens paper.
Store your microscope in a cool dry place. Always cover or return to the box
when not in use. If used "in the field" take care to keep the unit upright as the
eyepiece can fall out if tipped. Eyepieces and lenses should remain in place to
avoid dust in the tubes. Keep microscope slides in their proper storage unit
when not in use. Always use care with real glass and keep out of reach of
young children.
When lights seem dim, replace the batteries with fresh AA batteries. (Be sure
to dispose of used batteries properly.) The LED light bulbs have a long life span
and should not require replacing. If either bulb does not work, even after
installing fresh batteries, please call for service.
Proper care and use of this product can result in years of scientific study and
adventure. Enjoy!
