Scanning Orientation with Laser Aiming Pattern
Figure 2-8
The aiming pattern (or laser line) is smaller when the digital scanner is closer to the symbol and larger when it is
farther from the symbol. Scan symbols with smaller bars or elements (mil size) closer to the digital scanner, and
those with larger bars or elements (mil size) farther from the digital scanner.
The digital scanner beeps to indicate that it successfully decoded the bar code. For more information on beeper
and LED definitions, see Table 2-1
