1. FIG 6 is the process flowchart for recalling a name from memory 907 which is part of the dialing state 217 The process is started at 501 At 505 the user presses the go key 121 this is also shown in FIG 4 as transition action 319 Secondly the user must enter a data key 119 which repre sents the symbol closest to the name in which the user is trying to recall at 507 This puts the user into close proximity to the name in which he wants to recall For example on a 10 15 20 25 30 35 40 45 50 55 60 65 4 standard key input if the user was to recall Bill he would press data key 2 because it contains the letters A B and C Next the user would use the scroll keys located on the and keys to scroll either in ascending alphabetical order or descending alphabetical order at 509 until the name is located After the correct name is displayed on the radio telephone 101 the go key 121 is pressed at 511 this completes the process of recalling a name from memory 907 and is the transition state 331 noted in FIG 3 FIG 7 reveals the process which is used to enter phone numbers and corresponding names into the memory 907 of a radiotelephone 101 according to the present invention The process starts at 601 At 603 the user presses the go key 121 entering the symbol mode state 307 At 605 the user presses the go key 121 enter the inputting name and number state 311 Here the user selects the2. 309 pressing the go key 331 will place the 101 radiotelephone into the talking state 313 Once in the talking state 313 one may press the stop key 333 which will end the call and return the caller to the standby state 301 While in the symbol mode state 307 the user has the option of inputting a new name and phone number instead of recalling a name and phone number This can be accomplished by pressing the go key 323 thereby transferring from the symbol mode state 307 to the inputting name and number state 311 While in the inputting name and number state 311 pressing the go key 321 will return the user to the standby state 301 At any point in time when entering a sequence of data keys it may be necessary to clear one of the inputs or the entire data input depending upon how severe the mistake FIG 3 reveals the process for clearing data from the display 111 First the process starts at 401 at 403 the user enters the sequence of the data keys 105 the user then will visually check the display 111 to see if the data is correct at 417 At 405 if it is not correct the user must press and hold the stop key 109 If the user wants to clear the last data key input at 411 then the stop key 109 must be released after the first beep at 407 If the entire data key input is to be cleared at 413 the stop key 109 must be released after the second beep at 409 This process is repeated until the data displayed is correct then process is stopped at 415
