When you release the selector switch, the lifting column stops im-mediately.The switching technology causes a delay of approx. 2 seconds at theupper and lower end positions of the lifting column. After this time, youcan move the column in the opposite direction again by activating the se-lector switch.The lifting column is used to move the microscope into position for sur-gery prior to the surgical procedure.Do not constantly move the lifting column up and down, since otherwisea thermal cut-out will automatically deactivate the drive motor. If this oc-curs, the lifting column cannot be moved until the motor has cooleddown.Note: With a maximum activation time of one minute, the lift columnmust be turned off for at least nine minutes because the motor of the liftcolumn might overheat otherwise.3 4CAUTION Injury to the patient!• Do not activate the lifting column during surgery!• Do not use the lifting column for focusing.• When using a fundus viewing system which is installed between the sur-gical microscope and the patient, make sure that the patient is neitherput at risk nor injured:– by the motorized movement of the lifting column,– by the motorized focusing system,– by the movement of the suspension arm.
