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.

Scan LED Indicator

The Indicator LED bar on the mobile computer provides a visual indication of the scan status.

NOTE Imager decoding usually occurs instantaneously. The mobile computer repeats the steps required to take

a digital picture (image) of a poor or difficult bar code, as long as the trigger remains pulled.

NOTE Scanning procedures depend on the application and mobile computer configuration. An application may

use different scanning procedures from the one listed above.
