    Chapter 6). You may modify those defaults by using the QR-coded parameter menu given in Chapter 7. Settings made from the QR-coded parameter menu will be stored in the memory of the QS20P-A, so they will be retained even after the QS20P-A power is turned off.

  • Page 16: Chapter 4. Scanning Codes

    Label Target code • If the QS20P-A fails to read due to specular effects or other factors, change the scanning angle of the scanning window or the distance from codes, and try it again. (Specular effects occur when the reflection of the light from the target code becomes excessively strong.
  • Page 17 • Disabling reading of unnecessary types of codes may increase the scan- ning speed. NOTE Before reading labels, clean them if stained. Avoid using the QS20P-A in direct sunlight. The QS20P-A might fail to read NOTE correctly.

  • Page 18: Chapter 5. Features

    Chapter 5. Features Scanning If you press the trigger switch, the QS20P-A will turn the illumination LED on and become ready to scan. It will take approx. one second to make the QS20P-A ready for scan after depression of the trigger switch. Bringing the scanning window into contact with a target code will cause the QS20P-A to read the QR code and send it to the connected PC or external equipment automatically.
  • Page 19 When reading split QR codes, the QS20P-A beeps in a different way from usual. That is, when the QS20P-A reads the first split code, it beeps twice and enters the split code scanning mode. After that, each time it reads the subsequent split code, it beeps once.
  • Page 20 Up to 8 kilobytes of data transferable in Edit mode In Edit mode, QS20P-A can read split codes of up to 8-kilobyte data, store and edit them, and then transfer the restored data to the PC. If a restored code contains data exceeding 8 kilobytes, the QS20P-A will cause a reading error and clear the restored data.
