Aiming

Hold the digital imager scanner between two and nine inches (depending on symbol density; see
page 2-7) from the symbol, centering the aiming pattern cross hairs on the symbol.
The aiming pattern is smaller when the digital imager 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 imager scanner, and
those with larger bars or elements (mil size) farther from the digital imager scanner.
The digital imager scanner can also read a bar code presented within the aiming pattern but not centered. The top
