ABSTRACT:
Index letters representing different groups of dial memories are stored in an index letter memory. One of the dial memories is displayed on a display to be a starting memory, when a reference requesting signal is supplied from a key input unit to a whole memory or skip reference portion of a central processing unit, so that a whole memory or skip reference mode is carried out to refer to a dial memory indexed in each of the different groups by each of the index letters in a forward or reverse direction from the starting memory to following dial memories. In the whole memory reference mode, dial memories indexed by the index letters are referred for continuous groups of dial memories. In the skip reference mode, index letters of a number "n" are skipped in accordance with the pressing-on of a skip reference key provided in the key input unit by "n" times, so that a dial memory corresponding to an index letter following the skipped index letters is referred to be displayed on the display.
