Operation 203
Procedure
• Switch on the power switch of the suspension system.
Warning!
Looking directly into the light source, e.g. into the microscope objective
lens or light guide, may result in damage to the eye.
Avoid looking directly into the light source!
• Start with the lowest brightness setting on the suspension system and
gradually increase brightness up to the necessary and still admissible
level.
Warning!
Too much light intensity (brightness setting is too high) or excessive radi-
ation exposure times may lead to retinal injury in the patient's eye.
Adjust the illumination intensity as required for the selected type of illumi-
nation and the radiation exposure time. You will find the values recom-
mended by Carl Zeiss in the table "Maximum radiation exposure times"
on page 29.
• Check the system using the checklist.
• Swing the surgical microscope over the surgical field into an ergonom-
ic position within the working distance.
• Press the reset button on the X-Y coupling.
– The X-Y coupling moves to its center position.
– The focus adopts its initial position in the focusing range.
• Select the lowest magnification (zoom function on the foot control pan-
el).
• Look through the eyepieces and lower the surgical microscope using
the suspension arm until the surgical field comes into focus. This will
result in coarse focusing.
• Select the highest magnification (zoom function on the foot control
panel).
• Look through the eyepieces and activate the focusing function on the
foot control panel until the microscope is sharply focused on the sur-
gical field.
Note:
– If no red reflex is required, swing the retinal protection device into the
beam path.
