摘要

The input procedure is initiated by the input key (E) and this key can assign symbol input functions to the function keys normally used in other ways. A complete set of signs for the input of a text appears in several lines (ZA) and one of the lines can be selected by the line keys and provided with a recognition sign before the symbol input keys are pressed which gives the letter to be includes in the test display (TA). This can then be sent off by pressing the start key (ST). ADVANTAGE - With minimum of additional keys there can be a wide selection of visible signs or symbols, since each symbol input key is used for number of symbols.
