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.
Battery safety instructions
Always purchase the correct size and grade of battery most suitable for the intended use. Always replace the whole set of batteries
at one time; taking care not to mix old and new ones, or batteries of different types. Clean the battery contacts and also those of
the device prior to battery installation. Make sure the batteries are installed correctly with regard to polarity (+ and −). Remove
batteries from equipment that is not to be used for an extended period of time. Remove used batteries promptly. Never short-
circuit batteries as this may lead to high temperatures, leakage, or explosion. Never heat batteries in order to revive them. Do
not disassemble batteries. Remember to switch off devices after use. Keep batteries out of the reach of children, to avoid risk of
ingestion, suffocation, or poisoning. Utilize used batteries as prescribed by your country's laws.
