Intended Use
The Leica DM300 is an optical instrument for
improving the visibility of objects through
magnification and illumination. It is used for
observing.
Place of Use
The Leica DM300 microscope may be used only
in closed rooms and must be placed on a solid
surface.
The Leica DM300 can be used at +10 °C to
+40 °C. Protect the microscope from oil, chemi-
cals and extreme humidity. If it is used outdoors,
the microscope must be protected from dust
and moisture. Never use electrical instruments
outdoors and place them at least 10 cm away
from the wall and from flammable substances.
Avoid large temperature fluctuations, direct
sunlight and vibrations. These conditions
can distort measurements and micrographic
images.
In warm and warm-damp climatic zones,
the individual components require

Health Risks and Dangers of Use
Health Risks
Workplaces with microscopes facili-
tate and improve the viewing task, but
they also impose high demands on the eyes
and hand muscles of the user. Depending on
the duration of uninterrupted work at such a
workplace, impaired vision and problems with
the musculoskeletal system may occur. For this
reason, appropriate measures for reduction of
the workload must be taken:
ϘOptimum workplace layout
ϘFrequent changes of activity
ϘThorough training of the personnel, giving
consideration to ergonomic and organiza-
tional aspects
The ergonomic optical design and construction
of the Leica microscopes are intended to reduce
the exertion of the user to a minimum.
Danger of Infection
Direct contact with eyepieces can be a
potential transmission path for bacterial
and viral infections of the eye.
The risk can be minimized by the use of
personal eyecups.
Dangers during Use
ϘThe Leica DM300 may be connected to a
grounded socket only.
ϘThe Leica DM300 may be used when it is in
proper working condition only.
