This manual is an important part of the Leica

DM IL microscope and should be carefully

read before switching on and using the

instrument.

This manual contains important instructions and

information with regard to operating safety and

maintenance of the system. For this reason, it

should be carefully kept at hand.

Text symbols and their meaning:

General safety information

Only fuses of the specified type and rating may

be used as replacements. Never use repaired

fuses or short-circuited fuse holders.

Attention!

The instruments and accessories described

in this manual have been safety-tested and

checked for possible hazards.

Before modifying the instrument in any way

or combining it with non-Leica products not

covered by this manual, please always

contact your local Leica representative or the

main factory in Wetzlar!

Any unauthorised interference with the

instrument or use of the instrument for

applications for which it is not designed will

automatically void any warranty claim!

This instrument of Safety Category I has been

built and tested according to EN 61 010-1/

IEC 1010-1, Safety Standards for Electronic

Measuring Instruments, Electronic Regulators

and Electronic Laboratory Instruments.

Attention!

To maintain this condition and to ensure safe

operation, the user must note and adhere to

the directions and warnings contained in this

manual.

The mains plug may only be inserted into a

grounded socket.

The protection must not be jeopardised by using

an extension cable without ground conductor.

Any break in the ground conductor within or

outside the instrument or loosening of the

ground connection can render the unit

dangerous. Intentional severance is prohibited!

Attention!

Accessory devices connected to the

microscope which have a separate and/or

different power supply should be brought to

the same ground potential by connecting

them to the same grounding system. Contact

the service department in case of an

ungrounded mains supply .

Attention!

The electrical accessories for the micro-

scope are not protected against the

penetration of water which can result in

electrical shock.

Do not set up the microscope and its

accessories in the immediate vicinity of a

water outlet or in other places where water

may penetrate into the instrument.

Attention!

Before replacing fuses or lamps, always

switch off the power switch and disconnect

the power cord.

Attention!

Protect the microscope against excessive

temperature fluctuations which may lead to

condensation and thus damage the electrical

and optical components.

Attention!

When using immersion oil, take care to avoid

skin contact! Ask the supplier for a safety

data sheet!

Application

The Leica DM IL microscope is designed for

routine examinations of cell and tissue cultures,

liquids, and sediments.

Two basic microscope stands are available for

biologic applications. One is the standard bright

field version using the contrasting methods

bright field (BF), phase contrast (Phaco), and

Integrated Modulation Contrast (IMC), the other

is the fluorescence microscope which also

offers incident-light fluorescence in addition

to the three transmitted-light contrasting

techniques.

All microscope techniques and the required

accessories for the Leica DM IL are described

and explained in detail in the Operation section

of this manual, including the associated

functions and their use.
