• Bring the suspension arm in a position convenient for you and tighten
friction adjustment knob (1).
CAUTION Risk of injury caused by lowering of the surgical microscope!
• Never prepare the system for use above the patient.
• Never mount or remove accessory equipment on the surgical microscope
during surgery.
• Only use accessories expressly certified by ZEISS for combination with the
surgical microscope described in this manual.
• Never exceed the maximum permissible weight capacity of the suspension
arm (see Page 148).
• Rebalance the suspension arm after every change of equipment (see
Page 73).
• Tighten all friction knobs firmly.
WARNING Risk of injury caused by falling parts!
• Before every use and after re-equipping the system, make sure that
binocular tube (5) is securely locked in position. Make sure that securing
screw (4) and objective lens (3) or the objective lens carrier ring with
accessories have been firmly tightened!
CAUTION Confusing the assistant tube with the main observer tube
If the assistant tube is incorrectly connected to the main observer interface,
the stereo image of the surgical field will not appear correctly, and the surgical
field will produce an incorrect stereoscopic impression.
If the surgery is performed with this configuration, this may cause injury to
the anterior segment of the eye.
• Label the inverter tube as the assistant tube.
