Instructions on Use
The Leica DM750 M microscope may be
used only in closed rooms and must be
placed on a solid substrate.
Always position the Leica DM750 M
microscope so that you can discon-
nect it from the power supply at any time.
The power cable must remain accessible at all
times, because it is intended as a power discon-
nect 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 electri-
cal devices outdoors. Install electrical devices at
least 10 cm from the wall and away from flam-
mable 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.
Non-intended use
Never install any other plug or unscrew
any mechanical components unless
expressly instructed to do so in the instructions.
The devices and accessories described in
this instruction manual have been tested
for safety and potential hazards.
