Notes on installation and use
Safe working order
• Do not operate the equipment contained in the delivery package in
– explosion-risk areas,
– the presence of inflammable anesthetics or volatile solvents such
as alcohol, benzine or similar chemicals.
• Do not station or use the instrument in damp rooms. Do not expose
the instrument to water splashes, dripping water or sprayed water.
• Immediately unplug any equipment that gives off smoke, sparks or
strange noises. Do not use the instrument until our service represent-
ative has repaired it.

readily connect, make sure that they are appropriate for one another.
If any of the connectors are damaged, have our service representative
repair them.
• Do not use a mobile phone in the vicinity of the equipment because
the radio interference can cause the equipment to malfunction. The ef-
fects of radio interference on medical equipment depend on a number
of various factors and are therefore entirely unforeseeable.
• Potential equalization: If desired, the unit can be incorporated in po-
tential equalization measures. The potential equalization bolt is re-
quired for this purpose, see chapter "Description".
• Modifications and repairs on these instruments or instruments used
with them may only be performed by our service representative or by
other authorized persons.
• The manufacturer will not accept any liability for damage caused by
unauthorized persons tampering with the instrument; this will also for-
feit any rights to claim under warranty.

table, attach a sign to the instrument stating it is out of order and con-
tact our service representative.
Requirements for operation
Our service representative or a specialist authorized by us will install the
instrument. Please make sure that the following requirements for opera-
tion remain fulfilled in the future:
– All mechanical connections (details in the user's manual) which are
relevant to safety are properly connected and screw connections tight-
ened.
– All cables and plugs are in good working condition.
– The voltage setting on the instrument conforms to the rated voltage of
the line supply on site.
– The instrument is plugged into a power outlet which has a properly
connected protective earth contact.

Safety 13
• Pay special attention to warning symbols on the instrument (triangular
warning signs with exclamation marks), labels and any parts such as
screws or surfaces painted red.
• Do not cover any ventilation openings.
For every use of the instrument
• Always position the stand in such a way that the long extension of the
stand base points in the direction of the surgical field (if the instrument
is equipped with a base of this type).
• The transport casters must be retracted to ensure that the unit is se-
curely resting on its base (with instruments with retractable transport
casters).
• Avoid looking directly into the light source, e.g. into the microscope ob-
jective lens or a light guide.
• When the illumination is on, the light guide must be connected at both
ends. Otherwise there is a risk of fire or burn injuries.
• Make sure that the instrument has been switched off before you
change the xenon lamp module. When switched on, the ignition sys-
tem generates high voltage.
• The xenon illumination system is a high-intensity light source which -
if used improperly - can cause thermal injury to skin or tissue. Keep
the exposed tissue moist and provide sufficient irrigation. Carefully
monitor the effects of the illumination on the tissue, in particular in the
following cases:
– during prolonged procedures on skin and tissue using objective
lenses with a short focal length (short working distance),
– during procedures on tissue with a low blood supply,
– with high brightness settings of the xenon lamp.
• Since the xenon lamp provides high light intensity and generates light
with a spectrum similar to daylight, it must not be used for ophthalmic
applications.
• Any kind of radiation has a detrimental effect on biological tissue.This
also applies to the light illuminating the surgical field. Please therefore
reduce the brightness and duration of illumination on the surgical field
to the absolute minimum required.
After every use of the instrument
• Always use the main power switch of the instrument to turn it off.

Safety devices
1Release bar
Allows non-sterile persons to release the magnetic clutches of the
ceiling mount (floor stand).
2Adjustment screw for limiting the downward travel
Use this screw to set the minimum vertical distance (working distance)
from the surgical field. Check this setting before each surgical proce-
dure.
3Locking knob
for locking the suspension arm in its horizontal position.
Before removing or attaching a unit (microscope, tube, etc.), move the
suspension arm into a horizontal position. Pull out the locking knob
and turn it clockwise or counterclockwise through 180°, while slightly
moving the suspension arm up and down until the lock engages.
When locked, the suspension arm can no longer suddenly spring up-
ward when insufficient weight is attached. After attaching a unit, per-
form the balancing procedure.

The lamp module contains two xenon lamps. The second lamp is used
as a backup lamp which has to be swung into the illumination beam
path when the first lamp fails.
If the xenon lamp fails, open the lamp module as follows:
Press button (4). The lamp module is slightly ejected. Pull out the lamp
module all the way. Turn knob (1) through 180° until it snaps in. This
moves the backup lamp into the illumination beam path. Push the
lamp module all the way back into the lamp housing.
2Yellow indicator lamp
Lights when the lamp has failed. After activation and ignition of the
backup lamp, the yellow indicator lamp goes out again.
3Manual function
When the manual function has been activated, all electrical control
systems are inoperative. The lamp brightness is automatically ad-
justed to a fixed setting.
