Carefully lift the microscope from the case. Place one hand around the
microscope arm and the other under the base. For best results, use the
microscope on a flat sturdy surface. Always be mindful of your mirror and
light source. The more light that is reflected or transmitted through the hole in
the stage, the brighter and sharper the images will appear in the microscope
eyepiece.
Tip
Begin viewing at the lowest magnification or power and focus the object. Once
the images is focus increase magnification by turning the objective turret and
refocuses.
Always keep both eyes open when looking through the eyepiece. Doing so will
relive stress on you eyes
Caution
Be careful as you turn the focus knob so that the objective lens does not make
contact with a slide or the stage. This may cause damage to the slide and also to
the objective lens.
To prevent the wires attached to the light from breaking, never rotate the light
source a full 360 degrees.
Batteries
Place the microscope on its side. To remove the
protective plastic over, remove the screws with a
Phillips head screwdriver. Gently lift and the base will
open. Insert two “AA” batteries (not included) in the
base. Match the positive (+) and negative (-) poles
of the batteries with the markings on the base. To
replace lid, position it over the opening and replace
the screws.
Start Observing
Rotate the focus knob and lower the stage as for as it will go. Place the 20x
eyepiece into the microscope, if necessary. Turn the objective turret to the
shortest objective 15x.
Put one of the prepared glass slides under the stage clips and position the
prepared specimen over the hole in the stage.
Look through the eyepiece and slowly turn the focus knob until the specimen can
be seen in focus.
Rotate the focus knob to lower the body tube as far as it will go. Observe what
happens when you slowly move the light source or the mirror. Adjust the mirror or
light source to provide the amount of light that gives you the best image.
