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.

27. A portable radiotelephone handset comprising:
-
a standard housing having a front face; a keypad configured to be disposed on the front face; a plurality of faceplates, each faceplate configured for removable attachment to the front face of the standard housing for customizing appearance of the portable radiotelephone handset, at least one faceplate having a keypad cover movable between a first position and a second position, the keypad cover covering a portion of the keypad in the first position and exposing the portion of the keypad in the second position; a sensor for sensing attachment to the front face of the standard housing of a faceplate having keypad cover and providing a detection signal; and a controller which implements a first set of functions in response to a first state of the detection signal and a second set of functions in response to a second state of the detection signal. - View Dependent Claims (28, 29, 30)

31. A method for operating a communication device, the communication device including
a switch which is movable between a first position and a second position, and one of a first faceplate and a second faceplate disposed on the communication device, the first faceplate lacking a keypad cover and the second faceplate having a keypad cover, motion of the keypad cover actuating the switch between the first position and the second position when the second faceplate is disposed on the communication device and the keypad cover is present, the first faceplate including a fixed actuator for retaining the switch in one of the first position and the second position when the first faceplate is present, the method comprising the steps of: -
initially detecting a position of the switch, the position being one of a first position and a second position; in response to detection of the first position of the switch, determining that the communication device includes the second faceplate; subsequently, detecting position of the keypad cover in response to actuation of the switch by movement of the keypad cover; and in response to detection of the second position of the switch, determining that the communication device includes the first faceplate. - View Dependent Claims (32, 33)
