Press the buttons to send morse code! 'dot' for a small beep and 'dash' for long beep. For example to type 'O': "- - -" 3x dash To type 'H': ". . . ." 4x dot Press more button on to left corner if you need help. After pressing that button you cannot access the 'dot' and 'dash' buttons so press left arrow for 'dot' and right for 'dash'. ------------------------------------------------------------------------ Thank you In case you don't understand English: See down - .... .- -. -.- -.-- --- ..-
