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.

Battery safety instructions

Always purchase the correct size and grade of battery most suitable for the intended
use. Always replace the whole set of batteries at one time; taking care not to mix old
and new ones, or batteries of different types. Clean the battery contacts and also those
of the device prior to battery installation. Make sure the batteries are installed correctly
with regard to polarity (+ and –). Remove batteries from equipment that is not to be used
for an extended period of time. Remove used batteries promptly. Never short-circuit
batteries as this may lead to high temperatures, leakage, or explosion. Never heat
batteries in order to revive them. Do not disassemble batteries. Remember to switch off
devices after use. Keep batteries out of the reach of children, to avoid risk of ingestion,
suffocation, or poisoning. Utilize used batteries as prescribed by your country's laws.
