I have a different model- the Fischer Mewa Koma. Unfortunately no cord or knee lever so I've never tried it. The bed folds almost flat and the machine slides into a small briefcase type holder. If I recall correctly it has a dual voltage selector switch on the base. The Needlebar link has photos and information about your machine as well.

Just found another good link in German to both styles.
