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 ngers. 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 uids to
clean the optics.
Abrasive particles, such as sand, should not be wiped o lenses, but instead blown o or brushed away with a
so 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 aer you are nished 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
re and other sources of high temperatures.
When using the microscope, try not to use it near ammable materials or substances (benzene, paper,
cardboard, plastic, etc.), as the base may heat up during use, and might become a re 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 specications of your new
