a MagLabel sheet as illustrated in the following depiction:
GoFlight’s MagLabels are used to label the displays and buttons on the GF-166 for easy reference during flight. Using a pair of scissors, carefully cut out the labels that you wish to place on the panel to correspond with functions you have assigned using GF-Config.
Due to the thickness of the magnetic material, we recommend using a high-quality pair of scissors such as FISKARS or DURASHARP, which allow you to get a nice clean edge when cutting out the labels. Once cut out, the labels will fit into rectangular indentations on the GF-166 panel, and will be retained by the magnetism present in the material.
