Operating the MC31XX 2 - 21

Operational Modes

MC31XX with an integrated imager support three modes of operation, listed below. Activate each mode pressing

the Scan button.

•

Decode Mode: In this mode, the MC31XX attempts to locate and decode enabled bar codes within its field of

view. The imager remains in this mode as long as you hold the scan button, or until it decodes a bar code.

•

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

the MC31XX’s field of view. To accomplish this, move the aiming crosshair center dot over the required bar

code to decode only that 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 MC31XX’s field of view. This is useful

for capturing signatures or images of items like damaged boxes.

Imager Scanning

1. Ensure that a scan-enabled application is loaded on the MC31XX.

2. Aim the exit window at the bar code.

3. Press the scan button.

The red laser aiming pattern turns on to assist in aiming. Ensure the cross-hair is on top of the bar code.

The Scan LED lights red to indicate that scanning is in process, then lights green and a beep sounds, by

default, to indicate the bar code was decoded successfully. Note that when the MC31XX is in Pick List Mode,

the imager does not decode the bar code until the crosshair center dot touches the bar code.
