Chapter 4 Scanning Codes
(1) Turn ON the power to the scanner to make it ready for scanning.
(2) Bring the LCD of a mobile phone to the scanning window
of the scanner as shown
below.
The scanner reads a code shown on the mobile's LCD, outputs the code data read, beeps the speaker, and turns the
indicator LEDs blue.
Note:
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 successfully 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.
Note:
The double-read prevention timeout can be specified with the configuration software
(ScannerSetting_2D).
Note:
The scanner can read codes omnidirectionally. Note that a target code plus its margin should lie within the
scan range.
Note:
The scanner may fail to read depending upon the mobile model, the contrast or backlight setting, or the
LCD surface conditions (e.g., sticker pasted, scratches).
