Ensure the red scan beam covers the entire bar code. The Decode LED lights red to indicate that scanning
is in process, then lights green and a beep sounds, by default, to indicate the bar code was decoded
successfully.

Scanning Tips
Optimal scanning distance varies with bar code density and scanner optics.
•
Hold the scanner farther away for larger symbols.
•
Move the scanner closer for symbols with bars that are close together.
Adaptive Scanning
The RS419 contains the adaptive scanning feature that automatically adjusts the scan beam width for rapid
and easy scanning of bar codes from near contact to more than 200 inches away.
By default the RS419 is set to wide scan beam width. When the user presses the trigger, the RS419
determines the distance from the bar code. For close bar codes the RS419 sets a wide beam width and for far
bar codes it sets a narrow beam width. The RS419 uses distance, bar code type and material to determine the
correct scan beam width.
