Press button (1) until the motor of the balancing system stops. This decouples the surgical microscope from its suspension. After decoupling, the surgical microscope has adopted its center-ofgravity position. In that case the white ring (2, with marking) does not move if you turn the surgical microscope.

Continue pressing button (2) until the surgical microscope remains balanced in each position. Depending on the accessories attached, this may take some time (approx. 1 minute or longer). For checking, slightly lift the surgical microscope body and tilt it into different positions to see whether the surgical microscope body has been correctly balanced. If you pressed button (2) too long, you can correct the balance setting by pressing button (1). Tighten friction knob (3). 1

Final test OPMI® Sensera / OPMI® PROergo At the end of any balancing procedure we recommend to verify if the entire system was set up correctly. If the system will fail such test, you need to balance the system again and repeat the final test. •

Release the friction knob (1).

•

Try to hold the ring (2) in a fixed position while rotating the surgical microscope around the axis Y. Æ If this is not possible and both parts move together, the balancing act was successful and the system is safe to use. Æ If the ring (2) moves independent of the surgical microscope, the balancing procedure was not successfull and has to be performed again.
