Using the MC70 2 - 21

•

Pick List Mode: This mode allows you to selectively decode a bar code when more than one bar code is

in the EDA’s field of view. To accomplish this, move the aiming crosshair over the required bar code to

decode only this bar code. This feature is ideal for pick lists containing multiple bar codes and

manufacturing or transport labels containing more than one bar code type (either 1D or 2D).

•

Image Capture Mode: Use this mode to capture an image within the EDA’s field of view. This is useful

for capturing signatures or images of items like damaged boxes.

Scanning Considerations

Typically, scanning is a simple matter of aim, scan, and decode and a few quick trial efforts master it. However,

consider the following to optimize scanning performance:

•

Range

Any scanning device decodes well over a particular working range — minimum and maximum distances

from the bar code. This range varies according to bar code density and scanning device optics.

Scanning within range brings quick and constant decodes; scanning too close or too far away prevents

decodes. Move the scanner closer and further away to find the right working range for the bar codes

being scanned.

•

Angle

Scanning angle is important for promoting quick decodes. When laser beams reflect directly back into the

scanner from the bar code, this specular reflection can “blind” the scanner.

To avoid this, scan the bar code so that the beam does not bounce directly back. But don’t scan at too

sharp an angle; the scanner needs to collect scattered reflections from the scan to make a successful

decode. Practice quickly shows what tolerances to work within.

•

Hold the EDA farther away for larger symbols.

•

Move the EDA closer for symbols with bars that are close together.

Linear Scanning

1. Ensure that a scan enabled application is loaded on the EDA.

2. Aim the scan window at the bar code.

NOTE To enable Pick List Mode, download the Control Panel applet from the Symbol Support site at

http://support.symbol.com. Pick List can also be set in an application using a API command.

NOTE Scanning procedures depend on the application and EDA configuration. An application may use different

scanning procedures from the one listed above.
