  • Scroll down using the down button until label length is displayed
  • Change the value to suit your media length by using the left and right buttons then press return, an asterisk will appear next to your selection e.g. (25mm*)
  • Scroll down to the next value you need to change (label width) then use the left and right keys to change the value to one that suits. e.g. (50mm*)
  • Press return so the asterisk appears next to your chosen value. Return to the Icon menu anytime by pressing X
