Abstract
In an apparatus with a limited keypad (100, 300) several characters can be associated with each key. Characters associated with a key are determined on the basis of the language selected (200) as the operating language of the apparatus. The apparatus comprises a memory element (302) which includes a certain part (302a) for storing information indicating which set of the possible characters entered as push-button commands is in use as well as character set tables (302b-n) for selectively associating certain characters with each key on the basis of the information in said part (302a).
