Aiming the Imager
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.

such as the figure below on the left. The figure on the right, however, can not be decoded.
