2. Intended Purpose of the Microscope
2. Intended Purpose of the Microscope
The Leica DMI Series microscopes covered in
this manual are designed for biological, routine,
and research applications. This includes the ex-
amination of samples taken from the human body
in order to provide information on physiological
or pathological states or congenital abnormali-
ties; to determine the safety and compatibility
with potential recipients; or to monitor therapeu-
tic measures.
The Leica DMI Series is an additional develop-
ment of Leica’s proven inverted research mi-
croscopes, designed for cellular and tissue
examination, micromanipulation and microinjec-
tion techniques, microdissection, and confocal
microscopy. The Leica DMI Series is suitable
for universal deployment. All contrast methods
such as dark field, bright field, phase contrast,
DIC, fluorescence, and modulation contrast are
integral to the microscope and can be adapted
or changed quickly and easily. Variable illumi-
nation and imaging beam paths, as well as HCS
optics, modular accessories, and a comprehen-
sive range of peripherals complement the Leica
Microsystems inverted research stand.
IVD
The above-named microscopes comply with the
Council Directive 98/79/EEC concerning in vitro
diagnostics.
Caution!
The manufacturer assumes no liability for
damage caused by, or any risks arising from,
using the microscopes for purposes other
than those for which they are intended or not
using them within the specifications of Leica
Microsystems CMS GmbH.
In such cases the declaration of conformity
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 instruments accord-
ing to EN 60601-1. If a microscope is electri-
cally connected to a medical instrument
according to EN 60601-1, the requirements
defined in EN 60601-1-1 shall apply.
Not suitable for examining potentially infec-
tious specimens.
Only trained personnel may operate this type
of device.

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 whenever
the device is altered, modified or used in con-
junction 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

3. Safety Notes
Caution!
The microscope’s electrical accessory com-
ponents are not protected against water. Wa-
ter 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 ab-
solutely certain to switch off the main power
switch and remove the power cable.
Caution!
Per definition, the connection between
power supply cable and appliance inlet is
the power separator of this device. Thus, the
user is responsible for sufficient clearance
and accessibility of this area at all times.
Caution!
Do not use the microscope in altitudes ex-
ceeding 2000 m ASL/NL.
Caution!
Power plugs may only be plugged into an out-
let 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!
Peripheral devices with their own or sepa-
rate power supplies that are connected to
the microscope can have the same protec-
tive conductor potential by connecting them
to the ground screw on the back of the Leica
CTR4000, CTR6000, CTR6500 and CTR7000
electronics boxes. 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. The
use of incorrect fuses may result in a fire haz-
ard.

3. Safety Notes
3.3 Transport and storage
Caution!
Fully equipped, the microscope weighs more
than 18 kg. For transportation, the user has to
take care of the corresponding actions.
See also p. 30.
Caution!
Transport and storage in a range of -25°C
–+70°C and at a humidity not exceeding 80%
(non-condensing).
3.4 Safety Instructions
for Handling the Light Sources
Caution!
Light sources pose a potential irradiation risk
(glare, UV-radiation, IR-radiation). Therefore,
lamps have to be operated in closed hous-
ings and only after being mounted.
Never look directly into the beam path (blind-
ing hazard).
Connect the light guide to the microscope
first to prevent exposing the user to the high-
energy light output of the Leica EL6000 com-
pact light source.
Never look directly into the light emitted by
the light guide.
Caution!
Lamps and lamp housings may be hot!
They must be placed at least 10 cm away
from the wall and away from flammable sub-
stances.
Particulary, supply and data lines must not
encounter lamp housings!
3.5 Notes on handling laser devices
The microscope is not suitable for coupling laser
devices into the camera ports (refer to Chapter
4), as this creates a danger to the user from laser
radiation.
For use of the microscope with lasers, Leica
Microsystems offers special microscopes with
additional safety devices.
For further information, please contact your au-
thorized Leica Microsystems representative.
3.6 Notes on handling immersion oil
Caution!
When using immersion oil, take care to avoid
skin contact! Ask the supplier for a safety
data sheet!

3. Safety Notes
3.7 Safety Instructions
for Handling Acids and Bases
For examinations using acids or other aggressive
chemicals, particular caution must be taken.
Caution!
Be absolutely certain to prevent coming into
contact with these chemicals.
3.8 Disposal
To dispose of the product at the end of its service
life, please contact Leica Service or Sales.
Please observe national laws and regulations,
such as those implementing and enforcing the
WEEE EU Directive.
Note!
Like other electronic devices, the micro-
scope, its accessories and consumable ma-
terials must not be disposed of as regular
household waste.
