Abstract (en)
An apparatus and a method of shielding a user from electromagnetic radiation (9) emanated from a mobile telecommunication device (20) with operating components (1) having electromagnetic radiation blocking characteristics are presented, the method comprising steps for providing switchable bonds (2, 3) at different positions of an operating component (1) with electromagnetic radiation blocking characteristics, and for selectively switching the bonds (2, 3) depending on a selected operation frequency band to different RF-ground potential terminals available on at least one further operating component (4) of the telecommunication device. <IMAGE>
