2 - 30 MC3000 User Guide
Pick List Mode
Pick List mode allows the user to selectively decode a bar code when more than one bar code is in the mobile
computer’s field of view. By moving the aiming crosshair over the wanted bar code the user can selectively read
only the required bar code. This feature is particularly valued for pick lists containing multiple bar codes and
manufacturing or transport labels containing more than one bar code type (either 1D or 2D).
Aiming the Mobile Computer
The imager version of the mobile computer projects a laser aiming pattern (shown below) similar to those used on
cameras. The aiming pattern is used to position the bar code or object within the field of view.

Laser Aiming Pattern
To scan a symbol using the imager:
1. Center the symbol in any orientation within the aiming pattern. Ensure the entire symbol is within the
rectangular area formed by the brackets in the aiming pattern.

Centering Symbol in Aiming Pattern
The imager can also read a bar code presented within the aiming pattern but not centered, such as the figure
below on the left. The figure on the right, however, can not be decoded.
Figure 2-31
Bar Code not Centered in Aiming Pattern
Note that when the mobile computer is in Pick List Mode, the bar code is not decoded until the crosshair is
touching the bar code.
