  • Method and apparatus for entering numbers
    Patent number: 6622025
    Abstract: At least two key switches corresponding to one or more keys, for example on the side of the radiotelephone device or on the standard keypad of the radiotelephone device, can be used to dial a phone number, therefore, eliminating the need to use the entire standard keypad. One key switch is used to increment a candidate number and a one key switch is used to decrement the candidate number. The sound file corresponding to the candidate number scrolled is output through the speaker of the radiotelephone device. One key switch is used to select the candidate number and store the number as a digit of a phone number. The digit is stored within the call register. Once the entire phone number is selected and stored, a key switch is actuated to dial the entire phone number.
