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.
