2. Intended Purpose of Microscopes
2. Intended Purpose of Microscopes
The Leica DM6000 B microscope, to which this
user manual belongs, is designed for biological
routine and research applications. This includes
the examination of samples taken from the hu-
man body with a view to providing information
on physiological or pathological states or
congenital abnormalities, or to determining the
safety and compatibility with potential recipients,
or to monitoring therapeutic measures.
The Leica DM6000 M microscope is designed
for examinations in the field of materials
research.
All the above-named microscopes comply with
the Council Directive 98/79/EEC concerning in
vitro diagnostics. They also conform to the
Council Directives 73/23/EEC concerning
electrical apparatus and 89/336/EEC concerning
electromagnetic compatibility for use in an
industrial environment.
Caution!
The manufacturer assumes no liability for
damage caused by, or any risks arising from
using the microscopes for other purposes
than those for which they are intended or
not using them within the specifications of
Leica Microsystems Wetzlar GmbH.
In such cases the conformity declaration
shall cease to be valid.
Caution!
These (IVD) devices are not intended for use
in the patient environment defined by DIN
VDE 0100-710. Neither are they intended for
combining with medical devices according
to EN 60601-1. If a microscope is electrically
connected to a medical device according to
EN 60601-1, the requirements defined in
EN 60601-1-1 shall apply.

3. Safety Notes
3.1 General Safety Notes
This safety class 1 device is constructed and
tested in accordance with
EN 61010-2-101:2002,
EN 61010-1:2001,
IEC 1010-1:2001,
safety regulations for electrical measuring, con-
trol, and laboratory devices.
Caution!
In order to maintain this condition and to en-
sure safe operation, the user must follow the
instructions and warnings contained in this
operating manual.
Caution!
The devices and accessories described in
this operating manual have been tested for
safety and potential hazards.
The responsible Leica affiliate or the main
plant in Wetzlar must be consulted when-
ever the device is altered, modified or used
in conjunction with non-Leica components
that are outside of the scope of this manual.
Unauthorized alterations to the device or
noncompliant use shall void all rights to any
warranty claims!

3. Safety Notes
Caution!
The power plug may only be plugged into an
outlet equipped with a grounding contact.
Do not interfere with the grounding function
by using an extension cord without a ground
wire. Any interruption of the ground wire in-
side or outside of the device, or release of
the ground wire connection, can cause the
device to become hazardous. Intentional
ground interruption is not permitted!
Caution!
Through activating to the grounding
connection (earth screw on the back of the
Leica CTR6000 Electronics Box) ancillary
equipment with its own and/or extra power
supply may be brought to the same ground
wire potential. For connections without a
ground connector, Leica Service must be
consulted.
Caution!
Never use any fuses as replacements other
than those of the types and the current rat-
ings listed here. Using patched fuses or
bridging the fuse holder is not permitted.

3. Safety Notes
Caution!
The microscope’s electrical accessory com-
ponents are not protected against water.
Water can cause electric shock.
Caution!
Protect the microscope from excessive tem-
perature fluctuations. Such fluctuations can
lead to the accumulation of condensation,
which can damage the electrical and optical
components.
Ambient temperature: 15-35°C.
Caution!
Before exchanging the fuses or lamps, be
absolutely certain to switch-off the main
power switch and remove the power cable.

5. Unpacking the Microscope
The device is delivered in several boxes.
The stand box contains the following compo-
nents:
• Stand with integrated incident light axis and
objective nosepiece
• Specimen stage with stage bracket
• Power cable and PC connecting cable
• CD with Leica DMControl software package
• Instructions and list of microscope default
settings („Identification Sheet“)
The system box contains the microscope acces-
sories:
• Tube
• Eyepieces
• Objectives
• Condenser
• Lamp housings with accessories
• Fitting tool
• Depending on configuration, additional micro-
scope accessories such as filter cubes, etc.
The CTR6000 Electronics Box, the remote
control element SmartMove and the external
ebq 100 supply unit* are delivered in separate
packaging.
First, carefully remove all components from the
transportation and packaging materials.
Note:
If at all possible, avoid touching the lens sur-
faces of the objectives. If fingerprints do appear
on the glass surfaces, remove them with a soft
leather or linen cloth. Even small traces of finger
perspiration can damage the surfaces in a short
time. See the chapter, "Care of the Microscope"
→
p. 81, for additional instructions.
Caution!
Do not yet connect the microscope and pe-
ripherals to the power supply at this point!
5. Unpacking the Microscope

19
5. Unpacking the Microscope
Installation location
Work with the microscope should be performed
in a dust-free room, which is free of oil vapors
and other chemical vapors, as well as extreme
humidity. At the workplace, large temperature
fluctuations, direct sunlight and vibrations
should be avoided. These conditions can distort
measurements and micrographic images.
Allowable ambient conditions
Temperature 15-35°C
Relative humidity maximum 80% up to 30°C
Microscopes in warm and warm-damp climatic
zones require special care in order to prevent
the build up of fungus.
See the chapter, "Care of the Microscope" →
p. 81,
for additional instructions.
Caution!
Electrical components must be placed at least
10 cm from the wall and away from flamma-
ble substances.
Transport
For shipping or transporting the microscope
and its accessory components, the original
packaging should be used.
As a precaution to prevent damage from vibra-
tions, the following components should be dis-
assembled and packaged separately:
• Unscrew the objectives.
• Remove the condenser.
• Remove the stage.
• Remove the lamp housings.
• Disassemble the burner of 106 z lamp housing.
• Remove all moving or loose parts.

6. Assembly
6. Assembling the Microscope
The microscope components are logically as-
sembled in this order:
• Stage
• Condenser
• Tube
• Eyepieces
• Objectives
• Light sources
• Filter cubes/reflectors*
Only a few commonly used screwdrivers and
keys are necessary for assembly, which are in-
cluded in the delivery package.
When using intermediate systems and optical
accessories, the sequence may vary.
In this case, read Chapter
"6.10 Optional accessories" → p. 34.
