How to Scan
When the trigger is pressed, a red laser aiming beam is activated, enabling the user to align its hori-

figurable time-out
period elapses, then the red scan LEDs are activated to read the barcode.
If the barcode is not decoded before another configurable period has expired, the laser aiming beam
will begin blinking to allow the user to continue pointing the reader at the desired barcode.
NOTE
Barcodes :
To scan, center the illumination beam over the barcode as shown in
reader must "see" across the width of all of the bars. Move the reader further away from the barcode
to increase the scanning coverage area, and closer in to read very small barcodes.

(15° to 18°) to prevent unwanted reflection.
