A) For about 15 sec. the display shows alternately "rotor" and the
maximum permissible speed for the inserted rotor. Within this
period, it is possible to adopt this value by again pressing the
"start" key. The centrifugation is then continued.
B) Following onset of braking you must wait until the rotor has
stopped. By opening and closing the lid you reset the message
"rotor". After entering a permissible speed you can start anew.
