Using the Full Range Imager (Full Range Imager Models)
1.Turn on the Handheld Terminal, aim its CMOS Imager reader port toward the bar code or 2D code, and then press the trigger key.
The aimer in a round 
shape is emitted onto 
barcode.
2.The Handheld Terminal reads the code by emitting laser and red lights.
Indicator 2 (read operation indicator lamp) lights in green when the reading is successful.
Bar code and stacked 2D code Reading Guide
When you press the trigger key, LEDs in the Handheld Terminal emit laser and red lights. Align the laser pointer with the center of the bar code or 2D code you are trying to read. Take particular care aligning the light when there are other bar codes nearby.
When reading a bar code in large size, adjust the position of the Handheld Terminal so that the entire code is at proper distance. For small size, move the Handheld Terminal closer to it.
Important!
ξIf you have problem not properly reading a code, change the angle and/or the distance between the code and the Handheld Terminal and try reading it again.
ξA bar code and a stacked 2D code can be read from a distance of 130mm to 2,500mm (51/8" to 987/16"), and matrix 2D code can be read from a distance of 100mm to 20,000mm (315/16" to 65'73/8"). The actual reading distance depends on the symbology and the resolution.
ξFingerprints, dust, dirt, or stain on the CMOS Imager reader port can cause abnormal reading. Should the reader port become dirty, wipe it clean with a soft and dry cloth.
