Abstract
The present disclosure includes a discussion of an operating technique for a radiotelephone (101). The radiotelephone (101) has a memory (907), a display (127) and a keypad (117) which includes a first function key (107), a second function key (109), and a plurality of data keys (119). An actuation of the first function key (107) creates a first function key signal for recalling a telephone number. Once the telephone number has been selected, a subsequent actuation of the first function key (107) creates a second function key signal for connecting a call based on the telephone number. During the call, an actuation of the second function key (109) creates a third function key signal for disconnecting the call. A subsequent actuation of the second function key (109) creates a fourth function key signal for turning off the radiotelephone (213).
