Never begin a surgery with only one functioning xenon
lamp.
The LED can only be exchanged by a Leica Service person.
A dialog window informs you when the xenon lamp is losing
luminosity and is no longer sufficient. We recommend that
you keep a replacement lamp handy.

8.3.4 Setting the illumination field diameter
CAUTION
If the field diameter is greater than the field of view and the
light intensity is too high, uncontrolled tissue heating may
occur outside of the area visible through the microscope.
X
Do not set the light intensity too high.
With AutoIris the field diameter is automatically adapted to the size
of the field of view at the M530 optics carrier.
X
To adjust the illumination field diameter manually, use rotary
button (2).
Automatic adjustment AutoIris is deactivated.
X
To reactivate AutoIris press the Reset button (1).

If the illumination field diameter is blocked at a high light
intensity in a high magnification setting, and cannot be
adjusted automatically or manually, then the light intensity
must be reduced in order to protect the tissue.
If the field diameter is locked in a small position and cannot
be adjusted either automatically or manually, you can use
an OP lamp to better illuminate a large field of view (small
magnification position).
