The following provides guidelines for creating and insertion of legend cards for the membrane switch keypad assembly. Read all of the instructions prior to customizing and inserting the legend card. Border Printable Area (1.5) Typ .059 Card • Using the borders on the insertable legend card as a guide, be sure characters on the card are about 1.5mm (.059”) within these borders. This is the printable area. (1.5) Typ .059 • Legend characters may be drawn, printed, etc. Be sure that application choice is completely dry before inserting into membrane keypad assembly. Surface Sheet A B 9 C 6 8 D 5 3 7 4 2 P O 1 T S 0 Instructions for Inserting Legend Card • Note correct orientation of insertable legend card. Insert card under surface sheet, and use caution to avoid bending the membrane keypad assembly. Do not use pointed object to insert card, and do not remove surface sheet. • Align and center all legend characters within the squares of the surface sheet. C 3 2 1 4 7 • Peel off adhesive strip from the membrane keypad assembly. 5 8 6 9 B A • Smooth any wrinkles or air pockets from surface sheet. Protective Film Surface Sheet • The legend card is now firmly in place and cannot be removed. Adhesive Strip • Detach the protective film.
