Instructions on Use The Leica DM750 P microscope may be used only in closed rooms and must be placed on a solid substrate. Always position the Leica DM750 P microscope so that you can disconnect it from the power supply at any time. The power cable must remain accessible at all times, because it is intended as a power disconnect 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. In warm and warm-damp climatic zones, the individual components require special care in order to prevent the build-up of fungus.

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: O
Optimum workplace layout
O
Frequent changes of activity
O
Thorough training of the personnel, giving consideration to ergonomic and organizational aspects
Leica DM750 P User Manual
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 bacterial and viral infections of the eye. The risk can be kept to a minimum by using personal eyepieces for each individual or detachable eyecups.
Dangers during use O The Leica DM750 P microscope may only be connected to a grounded socket. O
The Leica DM750 P microscope may not be operated unless it is in proper functioning condition.
The microscope illumination is in the exempt group (risk group 0) according to EN 62471:2008 when used according to its intended use.
• of the illumination equipment – either Never look directly into the LED beam
with or without optical instruments – as this increases the risk class. Failure to observe this notice poses a risk of eye damage.
