To enter the FNC1 character, use the ASCII 202 character - Ê - (press and hold the ALT key while typing 0202). You may also type ^F1 to achieve the same effect.
FNC1 is required only at the end of variable length data section. It is not required as the last character in the bar code. For example:
- To encode (17) 041220, simply type 17041220 (Ê is not required with fixed length AIs)
- To encode (17) 041220 (30) 15, type: 170412203015 (Ê is not required at the end)
- To encode (30) 15 (400) 12345, type: 3015Ê40012345 (Ê is required after 15, because the AI of 30 is variable length)
