Chapter 5 Scanning Codes
Bring the QR Code to the scanning window of the scanner as shown below.
The scanner reads the QR Code, outputs the code data read, sounds the beeper, and turns the READ LED blue.
Notes ---------------------------------------------------------------------------------------------------
• The scanner supports the double-read prevention function that prevents the scanner from reading in the same code more than
once in succession even if you keep applying a code to the scanning window. To read the same code again after successful
read, therefore, pull the mobile away from the scanning window for at least half a second to release the double-read
prevention function.
Note that if you keep applying a low-quality code that cannot be read within half a second to the scanning window, the
scanner may double-read the code at intervals of half a second or longer.
• The double-read prevention timeout can be specified with the configuration software (QB Setting) and commands..
• The scanner can read codes omnidirectionally. Note that a target code plus its margin should lie within the scan range.
