Care and maintenance
Never, under any circumstances, look directly at the Sun, another bright source of light or at a laser
through this device, as this may cause PERMANENT RETINAL DAMAGE and may lead to BLINDNESS.
Take necessary precautions when using the device with children or others who have not read or who do not
fully understand these instructions. After unpacking your microscope and before using it for the first time check
for integrity and durability of every component and connection. Do not try to disassemble the device on your
own for any reason. For repairs and cleaning of any kind, please contact your local specialized service center.
Protect the device from sudden impact and excessive mechanical force. Do not apply excessive pressure when
adjusting focus. Do not overtighten the locking screws. 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. Children
should use the device under adult supervision only. Seek medical advice immediately if a small part or
a battery is swallowed.
