7 Use of the BIOM 4

Instruction manual BIOM 4 (G/54400/1011/en)
Then use the microscope footswitch control to zoom in to maximum magnification.
Now finely focus the image with the adjusting knob of the BIOM 4.
Only thus is a parfocal image (i.e. a sharp image at every magnification) guaranteed!
For the BIOM 4c only:
Adjust the sharpness of the image with the rocker of the combination foot switch,
both for initial focusing and for parfocally setting the image.
The microscope magnification should then be reduced to the minimum required, in
order to achieve as wide a fundus view as possible.
The use of the focusing function with the microscope foot pedal when the BIOM 4
is in use only changes the size of the image field ("keyhole effect").
Attention
During the whole process, make sure that the front lens cannot come into contact with
the cornea!
The cornea must be kept moist with a suitable fluid, to protect the cornea and to achieve
a good and clear view of the fundus.
Swing the BIOM 4 back to its parked position
After completing the surgery in the posterior segment, slide the safety insertion of
the BIOM 4 upwards by hand and swing the BIOM aside.
Deactivate the SDI.
For BIOM 4c and SDI 4c only
:
Swinging the BIOM 4c aside deactivates the SDI 4c.
