Operation
Note:
The dynamic speed control is based on the basic speed selected for fo-
cusing and the X-Y coupling in the speed mode.
If you have already set a high adjustment speed for focusing and the X-Y
coupling in the speed mode, dynamic speed control may possibly not be
effective across the entire zoom range, as the maximum adjustment
speed is reached beforehand.
In the extreme case, if you have set the basic speed for focusing and the
X-Y coupling to the maximum value of 10, dynamic speed control will
have no effect at all.
The upper display and key field (SPEED FUNCT:) in configuration mode
2 permits you to select high, medium or low speed adjustment, or none at
all.

Setting the lamp brightness as a function of the zoom setting (OPMI
Vario)
Menu item "LIGHT FUNCT:" permits you to select dynamic control of the
lamp brightness depending on the current zoom setting.
The lamp brightness you set in the basic mode is a fixed basic value of
the illumination intensity. Configuration mode 2 (LIGHT FUNCT:) permits
you to select automatic brightness control (AUTO) depending on the
zoom setting. The automatic function ensures uniform brightness of the
image over the full zoom range (0.4 to 2.4).
The transmission of the optical system decreases with increasing magni-
fication from zoom value 1 onwards. This is compensated by the auto-
matic function which increases the lamp brightness accordingly.
Use the middle display and key field (LIGHT FUNCT:) in configuration
mode 2 to choose between automatically controlled or constant bright-
ness of the lamp:
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-
