farther from the symbol. Scan symbols with smaller bars or elements (mil size) closer to the
unit and those with larger bars or elements (mil size) farther from the unit.
3. Hold the mobile computer between two and nine inches (depending on symbol density) from
the symbol, centering the aiming pattern cross hairs on the symbol.
4. Press and hold the trigger until the mobile computer beeps, indicating the bar code is
successfully decoded.
Scanning Tips
Optimal scanning distance varies with bar code density and scanner optics.
• Hold the scanner farther away for larger symbols.
• Move the scanner closer for symbols with bars that are close together.
Scanning procedures depend on the application and mobile computer
configuration. An application may use different scanning procedures from the
one listed above.
