Manual function
1 Manual key
The Manual key permits you to switch to manual operation. The mo-
torized control functions of the surgical microscope are deactivated.
The lamp brightness is automatically adjusted to a fixed setting, the
value being shown in the first display section.
When the manual mode is activated, the yellow LED is lit and the word
"MANUAL" blinks in the third display section.
The surgical microscope can no longer be operated via the foot control
panel, the handgrips or the display and key field.
In the manual mode, you can only switch the illumination on and off on
the foot control panel and release the magnetic brakes by pressing the
appropriate key on the surgical microscope.
The manual mode is retained even if you turn the power switch of the
instrument off and on again.
Press the Manual key once again to reactivate electronic control; the
display in the display and key field then returns to the basic mode.
