Your microscope with digital camera is a precision optical instrument and should be
treated with care at all times. Follow these care and maintenance suggestions and
your microscope will need very little maintenance throughout its lifetime.
Store the microscope in a dry and clean place.
Be very careful if using your microscope in direct sun light to prevent damage
to the microscope or your eyes.
Never point the microscope towards the sun or the camera can be damaged
and cease working.
Clean the outside surfaces with a moist cloth.
Never clean optical surfaces with cloth or paper towels as they can scratch
optical surfaces easily.
Blow off dust with a camel's hair brush or air blower off the optical surfaces.
To clean fingerprints off of optical surfaces, use a lens cleaning agent and
lens tissue available at most photo outlets and when cleaning do not rub in
circles as this may cause sleeks or scratches to occur.
Never disassemble or clean internal optical surfaces. This should be done by
qualified technicians at the factory or other authorized repair facilities.
Do not disassemble or take apart the microscope or damage can occur.
When handling glass specimen slides, use care as the edges can be sharp.
