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.
