– Provision of all accompanying documents required.

– Ensuring that the navigation system is only connected by person-nel who have undergone appropriate training and instruction.


Safety 13

– Contacting the local Carl Zeiss representative for any inquiries thatmay arise.

– Implementation of a procedure that guarantees the calibration ofthe surgical microscope which is absolutely vital for the use of theCarl Zeiss components "Surgical microscope on suspension sys-tem" in combination with a connected navigation system.This allows the calibrated surgical microscope combined with thenavigation system to be used like an optical pointer with a variablelength (corresponds to the working distance).

– Conducting complete functional testing, alignment and calibration(landmark test) of the navigation system after every subsequent in-stallation or exchange of navigation system components

– Incorporation of a regularly changing icon in the data injection dis-play of surgical microscopes equipped with a data injection sys-tem, i.e. the "heartbeat" of the navigation system must beconstantly visible for the user to permit data transmission errors tobe immediately detected.

• To check the accuracy of the overall system, perform the test specifiedby the navigation system manufacturer, e.g. the landmark test, alsousing the surgical microscope. This allows you to ensure that the ster-eotactic data has been correctly generated and transmitted to the nav-igation system without errors.

• Do not use any rotatable tube dovetail mounts when operating the sur-gical microscope with a connected navigation system. If mounts of thistype have been attached to the microscope, they must be carefullylocked in their central positions (tighten the knurled screws for rota-tion).

Requirements on the antenna design (non-Zeiss antennas)

• The antenna manufacturer must confirm that his antenna has beentested and certified for operation with the respective Carl Zeiss surgi-cal microscope on a suspension system in accordance with the re-quirements specified in the Carl Zeiss interface description"Navigation Interface for Carl Zeiss Surgical Microscopes".

Balancing the NC4 floor stand

Caution:– To ensure that you can guide the microscope almost effortlessly, you

must correctly balance four of the six axes of the system.

– Re-balance the system every time after you have re-equipped the mi-croscope.

– With the casters extended, the stand is not standing horizontally level.It is not possible to balance the NC4 floor stand in this state. An earlierbalance setting will only be active if the casters have been retracted.

Notes:– AB brake release keys:

After pressing the "AB" release keys you can move all six axes (sus-pension system and microscope axes) at the same time. When you letgo of the AB keys, the magnetic brakes will lock all axes in position atthe same time.

– SB brake release keys:In the Surgery mode: when you press the keys, you can move the mi-croscope in three directions (X, Y and Z). When you let go of the SBkeys, the magnetic brakes will simultaneously lock all axes in position.During balancing: depending on the mode selected, you can onlymove the axis to be balanced while pressing the keys. When you letgo of the SB key, the magnetic brakes lock the axis concerned in po-sition.

– When you press the brake release key (AB or SB), you can alwaysturn the stand and/or the microscope about their axes of rotation.When you let go of the keys, the magnetic brakes lock the axis in po-sition as described above.

Care of the unit

Warning!If possible, the systems and accessories should be cleaned immediatelyafter use. Contaminations should not be allowed to dry on the objects, asthis would make cleaning and disinfecting more difficult.If possible, machines should be used for disinfecting and cleaning. Fordetails, please also see the relevant notes on sterilization equipment.

Cleaning optical surfaces

The multi-layer T* coating of the optical components (e.g. eyepieces, ob-jective lenses) ensures optimum image quality.Image quality is impaired by even slight contamination. To protect the in-ternal optics from dust, the system should never be left without the objec-tive lens, binocular tube and eyepieces. After use, cover the system toprotect it from dust. Always store optical components and accessories indust-free cases when they are not being used.

Clean the external surfaces of optical components as required:

Caution:Do not use any chemical detergents or aggressive substances. Thesemay damage the optical surfaces.

• Remove coarse dirt (splashes of blood etc.) using distilled water towhich a dash of household dish-washing liquid has been added. Wipethe surfaces only with a damp, under no circumstances with a wetcloth.Any remaining marks can be easily removed using the following aids.

• For thorough cleaning of optical surfaces, use the optics cleaning set(Cat. No. 1216-071) or damp optics cleaning wipes (available fromspecialized dealers).

• Remove minor contaminations such as dust, streaks, etc. using aclean microfiber cleaning cloth (available from specialized dealers orunder Cat.No. 1254-655).

Auxiliaries from Zeiss: optics cleaning set, Cat. No. 1216-071

Suitable for the cleaning of objective lenses and eyepieces of the surgicalmicroscope at regular intervals.



Fogging of optical surfaces

To protect the eyepiece optics from fogging, we recommend using ananti-fogging agent.

Note:Anti-fogging agents provided by eyecare professionals for use with eye-glass lenses are also suitable for Zeiss eyepieces.

• Please observe the instructions for use supplied with each anti-fog-ging agent.

Anti-fogging agents do not only ensure fog-free optics. They also cleanthe eyepiece optics and protect them against dirt, grease, dust, fluff andfingerprints.

Cleaning mechanical surfaces

All mechanical surfaces of the equipment can be cleaned by wiping witha moist cloth. Do not use any aggressive or abrasive cleaning agents.

Wipe off any residue with a mixture of 50% ethyl alcohol and 50% distilledwater plus a dash of household dish-washing liquid.

Sterilization

The asepsis sets available from Carl Zeiss contain rubber caps, sleevesand handgrips which can be sterilized in autoclaves. We recommend thefollowing program for sterilization:

Sterile single-use drapes are available to cover the system.

Note:When draping the system, make sure there is enough slack in the drapesto allow for movement of the microscope carrier and surgical microscope.It is especially important that the drapes are completely loose around thehandgrips. The surgeon must be able to operate the controls through thedrape.

Sterilization temperature: 134° C

Sterilization time: 10 minutes



Disinfecting the control keys

To be able to use the system in the OR, for example, it may be necessaryto disinfect the control keys. We recommend using MELISEPTOL disin-fectant solution (B. Braun, Melsungen AG). Carl Zeiss keeps MELI-SEPTOL in stock, and you can also obtain it locally in many countriesfrom representatives of B. Braun, Melsungen AG.

Warning!– Wear disposable plastic gloves to prevent skin contact with the disin-

fectant.

– MELISEPTOL is inflammable (flame point at 31 °C). Please read theproduct information from B. Braun, Melsungen AG.

To apply MELISEPTOL, proceed as follows:

• Switch off the unit before disinfecting.

• Apply the disinfectant across the entire surface of the control panel.Do not let any disinfectant seep into the unit.

• Leave the disinfectant on the unit for approx. 30 minutes.

• Then carefully wipe the disinfectant off the surface using a sterile, lint-free cloth.

• Dispose of the gloves and cloth as normal waste.

Field-of-view diameterBeta min.(fmin / fmax) 93 / 163 mmBeta max.(fmin / fmax) 15 / 27 mm

Depth of field Double iris diaphragm for adjusting the depth offield. Image brightness decreases as depth offield increases. The brightness of data injection remains unaf-fected.



Illumination Coaxial fiber illumination supplied via S lightguide.Manually adjustable illuminated field (dia. 91 mm)to ”spot” illumination (dia. 16Ÿmm). These speci-fications relate to an f = 200 mm objective lens.Increased illumination intensity in a small illumi-nated field. Light source: Superlux 301 or anotherlight source specified by us.Additionally switchable auxiliary illumination forlightening up shadows. This illumination comesfrom a different direction and at a smaller angle ofincidence than the main illumination. The inten-sity of this illumination is approx. 10% of thestandard illumination.

Sliding mirror A sliding mirror has been integrated in the beampath. This mirror can be switched from the rearimage exit port (for an additional binocular tube)to the two side ports (for coobservation and pho-tographic documentation).

Coobservation port OPMI Neuro is equipped with a 180° coobserva-tion port (standard tube port). Simultaneous pho-tography and video recording (2D and 3D) arepossible.

Video port Integrated video port for1-chip 1/2" cameras and3-chip 1/2" cameras.Focal length f = 67 mmZeiss camera system (C-mount interface)

3D option with additional 3-CCD camera
