duty cycle, even when the imager exposure time is at its maximum in dark operating environments.

Concurrent mode provides the brightest appearance of the illumination LEDs of any of the imager operating modes. This mode may be useful for applications when an operator is using the illumination LEDs for aiming, such as in fixed mount, kiosk, or auto trigger applications.

Centering

Use Centering to narrow the imager’s field of view to make sure the imager reads only those bar codes intended by the user. For instance, if multiple codes are placed closely together, centering will insure that only the desired codes are read. (Centering can be used in conjunction with Aimer Delay on page 3-12, for the most error-free operation in applica- tions where multiple codes are spaced closely together. Using the Aimer Delay and Centering features, the imager can emulate the operation of older systems, such as linear laser bar code imagers.)
