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.
