Leica DM750 User Manual Safety Regulations 9

Instructions on Use

The Leica DM750 microscope may be

used only in closed rooms and must be

placed on a solid substrate.

The Leica DM750 microscope can be used in

clean rooms without any problems.

Always position the Leica DM750 micro-

scope 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 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. 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

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.

The responsible Leica aﬃliate must be

consulted whenever the instrument is

altered, modiﬁed or used in conjunction with

non-Leica components that are outside of the

scope of this manual!

Unauthorized alterations to the instru-

ment or noncompliant use shall void all

rights to any warranty claims.
