The button appears to be sticking on my Scanabout and the scan laser is staying on.

The scan laser should only be on when you are holding down the scan button. If you're scan laser is staying on after you release the scan button, then this indicates a rare condition with Scanabout's button.

We’ll need to replace your Scanabout if it’s doing this: please contact IntelliScanner Customer Care for assistance — we promise to get you a prompt replacement.
