1.2 Notes on instrument safety
If it becomes apparent that the safety measures are no longer effective, the device must be
taken out of service and secured against being used again
unintentionally. Please contact a
ZEISS service agency or the Carl Zeiss Microscopy Service to have the instrument repaired.
The Stemi 508 Information regarding instrument safety and installation conditions 435063-
6044-008 and the Stemi 508 Short operating instructions 435063-8044-
000 as well as the
operating instructions regarding the light sources also must be observed.
Do not operate the devices included in the scope of supplies in a potentially explosive
atmosphere, in the presence of volatile ana
esthetics or flammable solvents such as alcohol,
gasoline or similar substances.
The devices may only be operated by instructed persons who have been informed about the
possible risks in conjunction with the use of microscopes and the fields of appli
cation in
question. The microscope is a high-precision device that may be impaired in its performance or
even destroyed if handled improperly.
Before commissioning the instrument, make sure that the existing power supply is suitable for
the instrument.
Make sure that the mains plug is removed from the socket before the device is opened.
The devices are not equipped with special equipment protecting them from corrosive,
potentially infectious, toxic and radioactive or other samples that may be hazardous to health. If
you handle such samples, be sure to observe all legal require
ments, in particular the relevant
national accident prevention regulations.
The LED reflected-light illuminators and the LED transmitted-light illuminators have been
classified as belonging to LED risk group 2 acc. to DIN EN 62471:2009. Avoid looking directly
into the LED light.
If the device is operated with an external cold light source (high-
energy light), never look
directly into the fibre optic output of the cold light source. Otherwise, there is a risk of dazzling
and blindness.
Never cover the open light guide socket or the fibre optic output. There is a fire hazard!
In all cases avoid covering the open light guide socket or the fibre optic output with your hand
or other parts of your body. There is a risk of burns!

Safe disconnection from the power supply is ensured exclusively by removing the mains plug.
The switch on the microscope only switches into standby mode.
Do not
replace detachable mains cables by inadequately designed mains cables. Only the
specified power supply lines may be used.
The microscope and the controller K LED are equipped with a desktop power unit each
allowing line voltages in the range from 100 to 240 V ±10 %, 50 / 60 Hz, without the need for
changing the voltage setting on the device.
The desktop power unit meets the
requirements of protection class II (with protective
insulation). If its casing is damaged, put the power unit out of operation. The microscope may
only be operated with the desktop power unit supplied with the instrument.
Changing the lamps on the col
d light source is only admissible in accordance with the
manufacturer's operating manual. If the appropriate instructions are not complied with, there is
a risk of burns and explosion when changing the lamp.
Defective devices should not be disposed of with house
hold waste; dispose of them in
compliance with the statutory provisions.
Samples must also be disposed of appropriately in accordance with the applicable statutory
provisions and internal work instructions.
The stereo microscope Stemi 5
08 incl. its original accessories may only be used for the
applications described in this oper
ating manual. The manufacturer cannot assume any liability
for other applications, including those of individual
modules or single components.
Changes to and ma
intenance on this device and on devices which are operated together with
the microscope may only be performed by our service or by authorized persons. The
manufacturer of the devices does not accept any liability for damage due to unauthorized
interventions in the device. Moreover, such interventions invalidate all guarantee / warranty
claims.
Dirt and dust may impair the performance of the device. The device must therefore be
protected from such influences to the greatest possible extent and covered with the dust cover
when not in use. Before covering the device, always make sure that it is definitely switched OFF.
Considerable temperature fluctuations, direct exposure to sunlight and vibrations should be
avoided.
Blocking or covering ventilation louvers may result in heat accumulation which may damage the
device and in extreme cases even cause fire. Always keep venti
lation louvers free and do not
insert or allow any objects to fall into them. All electrical components and parts must be located
at a distance of min. 15 cm from flammable objects and walls.

If it is intended to operate the Stemi 508 with an external fibre optical cold light source, please
refer to the appropriate operating instructions incl. the safety provisions contained in them
before commissioning the light source.
The desktop power unit must not get into contact with moisture.
For transport over an extended distance, the device must be dismantled partially and
transported in its original packaging.
To transport the device over an extended distance, use the original packaging or the transport
case Stemi 305/508.
To connect the LED illuminators of the Stemi 305 system, six-pin modular connectors are used
which are known from telecommunications (type: RJ 12).
Only the LED illuminators pertaining to the Stemi 305 may be connected to the RJ 12 sockets in
the microscope body and in the stands of the Stemi
305. Only the connection cables supplied
with the device may be used.
The use of commercially available cables with RJ 12 connectors or the connection of fax units,
modems or other telecommunication equipment to the RJ 12 sockets of the Stemi
305 is
prohibited.

1.3 Warranty notes
The manufacturer guarantees that the device is free from material or manufacturing defects when
delivered. Any defects which may have occurred must be reported to us immediately and steps be taken
to minimize damage. If notified of such a defect, the device manufacturer is obligated to rectify it at his
discretion, either by repairing the instrument or by delivering an intact replacement. No guarantee is
provided for defects caused by natural wear (wearing parts in particular) and improper use.
The instrument manufacturer shall not be liable for damage caused by faulty operation, negligence or
any other tampering with the device, particularly the removal or replacement of instrument components,
or the use of accessories from other manufacturers. Such actions will render all warranty claims invalid.
No maintenance or repair work may be performed on the microscopes which exceed the activities
specified in this operating manual. Repair may only be performed by ZEISS Service or by persons
specifically authorized by it. Should any malfunctions occur on the device, please first contact the
Carl Zeiss Microscopy Service or, abroad, the ZEISS representative in your area.
