4 Locking lever for limiting vertical movement
The locking lever is used to set the lower limit position of the suspension
arm. This prevents the surgical microscope from making contact with the
patient, even if it is inadvertently lowered (see page 51).
When using a wide-angle observation system (e.g. BIOM 3 from Oculus),
which is usually installed between the surgical microscope and the patient,
make sure that the patient is neither put at risk nor injured by the motorized
focus adjustment system or the movement of the suspension arm.
Only use accessories expressly certified by ZEISS for combination with the
surgical microscope described in these instructions for use.
Injury to the patient's eye!
Incorrect operation of the fundus viewing system may cause injury to the
patient and impair the image quality. Perform the following steps to avoid
this hazard:
•
Perform a focus reset.
•
With the fundus viewing system swung out of the beam path, always
position the microscope body in such a way that the index dot (1) of
the microscope's focus is in the middle of the upper triangle (2) of the
marking.
•
2
Select a medium magnification (e.g. 1.0).
•
Lower the surgical microscope to the surgical field until the patient's
cornea is in focus.
•
Turn the locking lever for limiting downward travel clockwise; without
any patients, check that the suspension arm cannot be lowered any
further.
•
It is vital that you read the instructions for use of the fundus viewing
system (e.g. BIOM 3 from Oculus).
