Adjusting the limit of downward movement
The downward travel of the suspension arm must be limited in such a way
that no hazard is caused to the patient's safety even if the surgical micro-
scope is inadvertently lowered.
• Give adjustment screw (1) a few turns to loosen it.
• Press one of the magnetic brake release buttons on the surgical mi-
croscope and lower the surgical microscope until it can be focused on
the surgical field (depending on the focal length of the objective lens),
while at the same time allowing for a sufficient safety distance from the
surgical field.
• Turn adjustment screw (1) clockwise as far as it will go.
• Lower the surgical microscope again to its bottom stop and check the
safety distance.
