Using the microscope

Place your microscope on an even surface. The mirror acts as an illumination source, so make
sure that you choose your working place accordingly. During daytime an ideal spot is by the
window, in the evenings it should be well-lit by a bright lamp. Rotate the mirror, so that you see
a bright circle of light through the eyepiece. Do not, under any circumstances, point the mirror
at the sun, as this may cause permanent retinal damage.
Place a prepared slide on the stage and secure it in place with stage clips.
Use the focus knob until the objective lens almost touches the cover glass of the slide.
Avoid touching the slide with the objective lens, as this may damage on or the other. After
lowering the microscope tube, look through the eyepiece, then use the focus knob to bring the
tube up and focus the view.
For additional comfort during your observations you can incline the eyepiece and the stage by
pulling the microscope arm.

Care and maintenance

After unpacking your microscope and before using it for the first time check for integrity and
durability of every component and connection.
Do not touch the optical surfaces with your fingers. You can use a soft napkin or a cleaning
wipe, dipped in ether or absolute alcohol, to clean lenses. We recommend using special optics
cleaning fluids from Levenhuk. Do not use any corrosive or acetone-based fluids to clean the
optics.
Abrasive particles, such as sand, should not be wiped off lenses, but instead blown off or
brushed away with a soft brush.
Do not apply excessive pressure when adjusting focus. Do not overtighten the locking screws.
Protect the device from sudden impacts and excessive mechanical force.
Store the device in a dry, cool place away from dust, hazardous acids and other chemicals, away
from heaters, open fire and other sources of high temperatures. Do not use the device for
lengthy periods of time, or leave it unattended in direct sunlight. Keep the device away from
water and high humidity.
Be careful during your observations, always replace the dust cover after you are finished with
observations to protect it from dust and stains.
If you are not using your microscope for extended periods of time, store the objective lenses
and eyepieces separately from the microscope.
