A radiotelephone handset, including a display; a keypad; a cover moveable between a closed position and an open position in which the keypad is accessible to the user; and means for lighting the display and keypad to an extent limited by the position of the cover. When the cover is in a closed position, some, but not all of the keys and not the display, are obscured by the cover, when the cover is in the closed position, the lighting means may light only the display and those keys of the keypad not hidden by the cover. These keys may be used, for quite long periods, to, for example, operate a web browser, other over the air services where limited key access is sufficient, or simply to retrieve some information from the memory of the radiotelephone. During this period, while the cover remains in the closed position, the keys hidden by the cover remain deactivated. The cover can be a slide or a flip.
