"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.
When the manual mode is activated, the yellow LED is lit and the word
"MANUAL" blinks in the third display.
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 appro-
priate keys on the surgical microscope.
The selection of 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.
