Abstract
A communication device (1600) such as a portable radiotelephone handset features interchangeable faceplates including a first faceplate (1604) and a second faceplate (1804) which are removably attachable to a housing (1602). At least one of the plurality of faceplates includes a movable element (1802) such as a keypad cover. A sensor such as a switch (1574) detects the presence of the movable element (1802) and provides a detection signal to a controller (1560) which varies the operation of the communication device (1600) in response thereto.
