Instructions on use
Intended use
The Leica DM500 and DM500 B microscopes are optical instrument which use magnification and illumination to improve the visibility of objects. It is used for observing and documenting.
The Leica DM500 and DM500 B microscopes may be used only in closed rooms and must be placed on a solid floor.
The Leica DM500 or DM500 B microscopes can be used in clean rooms without any problems.
• Position the Leica DM500 or DM500 B microscope so that it can be disconnected from the power supply at any time. The power cord must remain accessible at all times, because the power supply is foreseen
as mains disconnecting device.
Place of use
Only use the instruments in closed, dust free rooms and between +10 °C and +40 °C. Protect the devices from oil, chemicals and extreme humidity. If using the devices outdoors, protect them from dust and moisture. Never use electrical devices outdoors. Install electrical devices at least 10 cm from the wall and away 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 special care in order to prevent the build-up of
fungus.
Non-intended use
•Using the instrument in any way contrary to the specifications in the user
manual can lead to bodily harm and damage to objects. Doing so can impair the functions of the protective measures provided.
Never install any other plug (NEMA 5-15P) or unscrew any mechanical components unless expressly instructed to do
so in the instructions.
CAUTION: Risk of explosion if battery is replaced by an incorrect type. Dispose of used batteries according to the instructions.
The devices and accessories described in this operating manual have been tested
for safety and potential hazards.

Health risks and dangers of use
Health risks
Workplaces with microscopes facilitate 
and improve the viewing task, but they also impose high demands on the eyes and
holding muscles of the user. Depending on the duration of uninterrupted work, asthenopia and musculoskeletal problems may occur. For this reason, appropriate measures for reduction of the workload must be taken:
ϘϘ Optimum workplace layout
ϘϘ Frequent changes of activity
ϘϘ Thorough training of the personnel, giving consideration to ergonomic and organizational aspects
The ergonomic design and construction of the Leica microscopy series are intended to reduce the exertion of the user to a minimum.
Danger of infection
•Direct contact with eyepieces is a potential transmission method for viral
infections of the eye.
The risk can be kept to a minimum by using personal eyepieces for each indi-
vidual or detachable eyecups.
Dangers during use
ϘϘ The Leica DM500 or DM500 B microscope may only be connected to a grounded socket.
ϘϘ The Leica DM500 or DM500 B microscope may not be operated unless it is in proper functioning condition.
LED Klasse 1 /Class 1 LED Product
The illumination meets laser class 1 requirements in accordance with IEC 60825-1 "Safety of LED products".
Caution: Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure!
