• Do not use any rotatable tube dovetail mounts when operating the sur-
gical microscope with a connected navigation system. If mounts of this
type have been attached to the microscope, they must be carefully
locked 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 been
tested 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".
• The following requirements, in particular, apply to the antenna:
– The surgical microscope with accessories and the antenna must
not exceed the admissible total weight (see label or the chapter
"Technical data").
– The antenna must not project over the bottom edge of the micro-
scope body in the direction of the surgical field.
– The antenna must neither obstruct the movement and adjustability
of the accessories which can be used on the surgical microscope
(usually a stereo coobservation tube, a camera adapter, a face-to-
face tube for spinal surgery, MM6 laser micromanipulator) nor col-
lide with these accessories.
– The antenna configuration must be implemented in such a way
that the localizer camera can always "see" the diodes or trackballs
when the surgical microscope and its accessories are in their usual
positions.
– When the system's internal antenna wiring is used, the EN60601-
1-2 standard (electromagnetic compatibility) must be complied
with.
– The output power of the LEDs or infrared LEDs (IRED) must al-
ways comply with the IEC 60825 laser safety standard, even in the
event of cable defects.
– The failure of one or several LEDs of the antenna may impair nav-
igation or lead to navigation failure. Take the necessary precau-
tions.
