Balancing the front-to-back tilt motion
For initial balancing or after a change of the accessories, proceed as follows:
• Deactivate the magnetic brakes by activating the Off button in the
Magnetic Brakes menu and then pressing the Enter button. The magnetic
brakes are now off.
• Press the release button (5) to open the magnetic brake.
• Loosen friction knob (4).
• Press the button (1) until the motor of the balancing system stops.
This decouples the microscope body from its mount.
Check zero position: The triangle and the line must coincide. If they don't,
readjust manually.
The microscope has been decoupled from its suspension and has
adopted its center-of-gravity position (zero position) if the white ring
with marking (3) does not move when you turn the microscope.
• Tap the key (2).
Allow the microscope to hang in its center-of-gravity position while you
press the button (2).
After approx. 15 seconds, the microscope body has again been coupled on
its suspension. You can check this: when you move the microscope body,
the white ring (3) also moves.
• Continue pressing button (2) and check whether the microscope body
remains balanced in every tilt position. Depending on the accessories
attached, this can take some time (approx. 1 minute or longer). To check
this, slightly lift the microscope body and tilt it into different positions to
see whether the microscope body has been correctly balanced.
• If you have pressed button (2) for too long, you can correct the balance
by pressing button (1).
NOTE Unintentional movement of the system
With an incorrectly balanced system uncontrolled movements of the
suspension system may occur.
• If uncontrolled movements occur, move the surgical microscope,
by overcoming the braking effect, into a position in which the patient is
not put at risk.
