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. Laser light reflecting
directly
back into
the scanner from the bar code is known as specular reflection. This strong light can “blind”
the scanner and make decoding difficult. The area where specular reflection occurs is known
as a “dead zone.”
You can tilt the scanner up to 65° forward or back and still achieve a successful decode.
Simple practice quickly shows what tolerances to work within.
