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.
