Targeting - Code CR1200 User Manual

3.2 - Targeting

The CR1200 targeting implementation projects two LED-generated images to aid you in properly positioning and focusing
the reading operation.
Figure 3.2 graphically displays the fi eld of view of the CR1200 reader and shows the areas of that fi eld of view where
various codes can be read. Targeting the code becomes more important as the size of the code decreases and the density
increases.
The optimal distance to read a code is 3.8" (9.7 centimeters). The LED targeting guides projected by the CR1200 help to
detect this optimal reading distance.
