A new distinct cultivar of Otacanthus plant named \u2018Calanda\u2019, characterized by its compact plant habit; dense and bushy plant form, mainly due to upright stems; deep violet colored corolla and a white throat spot; and less need for chemical growth retardation, due to plant having shorter internodes, shorter branches and shorter plant height. A first wireless communication section first performs wireless communication using a first frequency band and a second wireless communication section performs second wireless communication using a second frequency band with which at least a part of the first frequency band overlaps. The coupling insert is displaceable relative to the coupling member or an actuating member such that an axial movement of the coupling insert relative to the coupling member or actuating member produces an unlockinglocking movement of the engagement section in a direction transverse to the attachment longitudinal direction.
