Translation of secondary & footer menu in mobile devices

I have activated secondary & footer menu in mobile devices. Before doing this I have translated the complete theme into german using the CodeStyling Localization-plugin generating a german mo-file. The displayed buttons/menu areas for the secondary & footer menu in mobile devices are still kept in english. In which way can I change the displayed "Menu" an "Footer Menu" into german language? All the rest ist translated yet! http://www.olaf-moellenkamp.de (unter construction!)
