Vario: setting the lamp brightness as a function of the zoom
setting
Configuration mode 2 permits you to select dynamic control of the lamp
brightness as a function of the zoom setting.
The lamp brightness selected in the basic mode is a fixed, basic bright-
ness of the illumination. In configuration mode 2 (LIGHT FUNCT:), you
can set "Brightness as a function of the zoom position" (LIGHT FUNCT:)
to automatic (AUTO). The automatic function ensures that you have an
image of constant brightness across the entire zoom range (0.4 to 2.4).
From zoom value 1 onwards, the transmission of the optical system de-
creases with increasing magnification. The automatic function compen-
sates for this by increasing the lamp brightness appropriately.
The middle section of the display and key field (LIGHT FUNCT:) in confi-
guration mode 2 permits you to choose between automatically adjusted
or constant lamp brightness:
Warning!
Starting out from the basic brightness set in the basic mode, dynamic
brightness control adjusts the lamp brightness to higher zoom values by
increasing it up to the maximum. As a result, the tissue in the surgical field
may be subjected to excessive radiation.
You will not be aware of this while looking through the surgical micro-
scope, as the image you see displays constant brightness throughout the
zoom range. Only when looking directly at the surgical field will you notice
that the brightness of the illumination varies, depending on the zoom set-
ting.
Note:
If you have selected a relatively high basic brightness in the basic mode,
the automatic function may not be able to sufficiently compensate for re-
duced transmission of the optical system.

MANUAL
Path: The basic mode is automatically displayed after the instrument has
been switched on.
To access configuration mode 2 from the basic mode, go via con-
figuration mode 1.
For this, simultaneously press the "MODE" and "STORE" keys
twice in succession:
1. Jump from the basic mode to configuration mode 1
2. Jump from configuration mode 1 to configuration mode 2.
