In the example below, the gray area is the full imager field of view and the white
area is the centering window. Bar Code 1 will not be read, while Bar Code 2 will
be.
AutoTrigger
Two AutoTrigger Modes are available: Scan Stand and Presentation Mode.
When a unit is in Scan Stand mode, it remains idle as long as it sees the Scan
Stand symbol. (See Scan Stand Symbol that follows.) When a different co de is
presented, the Imager is triggered to read the new code.

Note: The scanner automatically adjusts the illumination LEDs to the lowest ligh t

level possible to maintain a good lock on the Scan Stand symbol.

Presentation mode is for those applications where a scan stand will not work, i.e.,
when large packages must be scanned. To program the devi ce for pre sentation
mode, refer to "Presentation Mode"on page 2-24.
