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.

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.
