4. Upon successful decode, the scanner beeps and the LED turns green. (For more information about beeper and

LED definitions, see Table 2-1 and Table 2-2.)

Scan line lengths vary depending on the scan line width selected (see Scan Line Width on page 4-

8). A full scan line width is the default. Medium and short scan line widths are useful for scanning

menus or pick-lists.

Aiming

On a typical UPC 100% hold the scanner between contact and 19 inches from the symbol (see Decode Zone on page 2-

10). When scanning using a single-line scan mode, ensure the scan line crosses every bar and space of the symbol.
