Cash register (4)
'cash register' is the definition.
(I know that cash register can be written as till)
This is the entire clue.
(Other definitions for till that I've seen before include "Cultivate - cash drawer" , "Work as farmer" , "Cultivate - where the money goes" , "Money box" , "Checkout - cultivate (land)" .)
(Other definitions for note that I've seen before include "Musical tone" , "Memo; tone" , "Do, re or mi?" , "Memo; pay attention to" , "Short record or letter" .)
