Aiming

Scan the Entire Symbol

•Your scan beam must cross every bar and space on the symbol.
•The larger the symbol, the farther away you should hold the scanner.
•Hold the scanner closer for symbols with bars that are close together.
•A short, high tone beep indicates a good decode.

Hold at an Angle

Do not hold the scanner directly over the bar code. In this position, light can
bounce back into the scanner's exit window and prevent a successful decode.
