Abstract
The housing of a hand held portable telephone has only a limited amount of surface area for providing a number of functions such as providing for a microphone, a receiver, a ringer, a keypad, an information display panel, a panel light, and a control key. By a reoperation of a control key, some equipment on the surface area is reused to perform a second function without requiring additional surface space.
