Using the C-MOS Imager (DT-X7M30E/DT-X7M30R)
1. Turn on the Handheld Terminal, position its C-MOS Imager reader port near the bar
code or 2D code, and then press the Trigger Key.
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 frame 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 enclosed within the laser frame. For small size, move the
Handheld Terminal closer to it.
Important!
If 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.
A bar code can be read from a distance of 40mm to 410mm (1

" to 16

/

"),
and a stacked 2D code can be read from a distance of 50mm to 250mm (1
15
/
16
"
to 9

/

") and matrix 2D code can be read from a distance of 60mm to 150mm
(2

" to 5

/
16
"). The actual reading distance depends on the symbology and the
resolution.
Note that a special reader application is required to read bar codes and 2D
codes.
Fingerprints, dust, dirt, or stain on the C-MOS Imager reader port can cause
abnormal reading. Should the reader port become dirty, wipe it clean with a soft
and dry cloth.
