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.
