Reading Techniques
The view finder projects an aiming 
beam that should be centered over 
the bar code, but it can be 
positioned in any direction for a 
good read. 
Hold the scanner over the bar code, 
pull the trigger, and center the 
aiming beam on the bar code.
The aiming beam is smaller when 
the scanner is closer to the code and larger when it is farther from the 
code.  Hold the scanner close to smaller bar codes, and farther away 
from large bar codes to get a proper read.  
If the bar code is highly reflective (e.g., laminated), you may need to 
tilt the scanner at an angle so the bar code can be scanned.
