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.
·
Seek medical advice immediately if a small part or a battery is swallowed.
