includes bug specimens to help you get
started.

of the stage plate.
2. Press the power button (9) to turn on the
upper illuminator (8).
3. Look through the eyepieces and gradually
turn the focus knob (7) until the
specimen comes into focus.
NOTE: You may need to adjust the interpupillary
distance of the eyepieces for better
viewing. Rotate the eyepieces up and
down to adjust the eyepiece distance.
TIP: You can further illuminate a specimen
by using an additional source of lighting
such as, a desk lamp, table lamp, bright
overhead light, or natural light.
CARE, MAINTENANCE
AND WARRANTY
Your Celestron Labs microscope is a
precision optical instrument and should be
treated with care at all times. Follow these
care and maintenance suggestions and your
microscope will need very little maintenance
throughout its lifetime.
• When you are done using your
microscope, remove any specimens left
on the stage.
• Turn off the power and unplug the power
cord (if applicable).
• Always place the plastic bag or dust cover
over the microscope when not in use to
help keep it clean.
• Store the microscope in a dry, clean
place.
• Be very careful if using your microscope
in direct sunlight to prevent damage to
the microscope or your eyes.
• To carry your microscope, place one hand
on the “arm” of the microscope and the
other hand under the base for support. Do
not grasp your microscope by the focuser
knob or head.
• Clean the outside surfaces (metal and
plastic) with a moist cloth.
• Always unplug any cords before cleaning.
• Never clean optical surfaces with cloth or
paper towels as they can scratch optical
surfaces easily. Instead, use an air blower
or camel hair brush.
• To clean fingerprints off of optical
surfaces, use a lens cleaning agent
and lens tissue available at most photo
supply stores. When cleaning, do not rub
in circles as this may cause streaks or
scratches.
• Never disassemble your microscope or
clean internal optical surfaces. Only
qualified technicians at the factory or an
authorized repair facility should attempt
these repairs.
• When handling glass specimen slides, use
care, as the edges can be sharp.
