Abstract
A telephone for mobile application affords hands-free operation when the handset is seated in a cradle and hand-held operation when removed from the cradle. The two modes are automatically sensed by a reed switch in the handset operated by a magnet in the cradle. The back of the handset, which is accessible when in the cradle, contains a back keypad and a back display, and the front of the handset contains a front keypad and a front display along with a microphone and an earpiece. When the reed switch senses hands-free mode only the back keypad and display are enabled, along with an external speaker and microphone. When hand-held mode is sensed, the front keypad, display and audio functions are enabled.
