Abstract
An arrangement for and a method of reading bar code symbols on a target to move a light beam emitted by a light source in a multiple line, scan pattern during a scan period in a first operational mode. Upon selection of a second operational mode by a user, a controller intermittently operates and energizes the light source to emit the light beam for a working time period which is less than, and a fraction of, the scan period to generate a single scan line across the symbol.
