Data Capture

• Angle: Scanning angle is important for quick decodes. When the illumination/flash reflects directly back
into the imager, the specular reflection can blind/saturate the imager. To avoid this, scan the barcode
so that the beam does not bounce directly back. Do not scan at too sharp an angle; the scanner needs
to collect scattered reflections from the scan to make a successful decode. Practice quickly shows what
tolerances to work within.
• Hold the device farther away for larger symbols.
• Move the device closer for symbols with bars that are close together.
NOTE: Scanning procedures depend on the app and device configuration. An app may use different
scanning procedures from the one listed above.
Scanning with Internal Imager
To capture barcode data:
1. Ensure that an application is open on the device and a text field is in focus (text cursor in text field).
2. Point the top of the device at a barcode.

3. Press and hold the Scan button or Trigger.
The red laser aiming pattern turns on to assist in aiming.
4. Ensure the barcode is within the area formed by the cross-hairs in the aiming pattern. The aiming dot is
used for increased visibility in bright lighting conditions.
The Scan LEDs light green and a beep sounds, by default, to indicate the barcode was decoded
successfully. Note that when the device is in Pick List Mode, the device does not decode the barcode
until the center of the crosshair touches the barcode.
