How have acquired the learning management in a school the scanner. There are thousands of books on the school year barcodes (only numbers, no text) zurückzuscannen and issue again next year. That all works fine. By radio links are up to 6-7 meters (all we need, therefore, no greater distance tested) no problem.
The scanner battery is charged via USB, can be done on the computer.
For scanning you have to press and hold again, then he wakes up and is ready. The rest is intuitive. Instructions poor, but also no longer required.
