Do not touch the optical surfaces with your fingers. To clean the device exterior, use only special
cleaning wipes and special optics cleaning tools 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 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 the device 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.
Store the device in a dry, cool place away from hazardous acids and other chemicals, away from
heaters, open fire and other sources of high temperatures.
When using the microscope, try not to use it near flammable materials or substances (benzene, paper,
cardboard, plastic, etc.), as the base may heat up during use, and might become a fire hazard.
Always unplug the microscope from a power source before opening the base or changing the
illumination lamp. Regardless of the lamp type (halogen or incandescent), give it some time to cool
down before trying to change it, and always change it to a lamp of the same type.
Always use the power supply with the proper voltage, i.e. indicated in the specifications of your new
microscope. Plugging the instrument into a different power outlet may damage the electric circuitry of
the microscope, burn out the lamp, or even cause a short circuit.
Seek medical advice immediately if a small part or a battery is swallowed.
