About the questions you had in our wireless scanners, hope you can find the answer through this article.


In the process of using the wireless barcode scanner, you may encounter the following problems:

1. Startup Abnormality

2. Communication Abnormality

3. Transmitted data is incorrect


Next, let us see how to solve it.


  • Startup Abnormality

(1) The battery is dead. Please use a 5V/1A charger or connect it to the USB port of a computer for charging. The red indicator light will light up when charging, indicating the charging status; the red indicator light will turn off when fully charged, indicating the fully charged status. In addition, you can also query the power level by reading the setting code of "Display Power", and the power data will be output to the device connected to the scanner.

(2) The system is locked. When turning on the machine, if you haven't wait it to finish the power-on and press the scan button quickly, the scanner may lock the scanning system and fail to turn on. If it is the A-9512/A-9516/A-9595/A-9599 series, let it sit quietly for 5 minutes to turn it off; if it is a series of other models, you can directly restart it by pressing the reset button at the tail. When using it again, please touch the scan button first, wait for the power-on sound to sound and the blue indicator light to light up, and then scan the code after the device is successfully connected.

(3) The device protection circuit is damaged because the user connected a charger with a voltage higher than 5V. In this case, it needs to be returned to the factory for repair.


  • Communication Abnormality

(1) Pairing failed. Please check the indicator light color. If pairing is successful, it will be blue.

(2) Pairing error. If your scanner has both wireless receiver and Bluetooth function, please re-pair to ensure that the wireless communication method is consistent with the user interface. For specific pairing methods, please refer to its manual or watch the following video.


  • Transmitted data is incorrect

(1) Incomplete data.

a. The third-party input methods will intercept the output data and perform secondary editing, resulting in incomplete data output. It is recommended to use the US input method keyboard.

b. Some barcode data needs to be fully output through settings. For example, although the UPC-E barcode displays 8 characters, it generally only transmits 6 characters by default. In some software, if it requires 8 bits to be transmitted, you can consult the seller to obtain the setting code for the start character and the check bit.

c. The scanner transmits too fast, and data loss may occur in some devices. You can consult the seller to obtain the setting code for output delay.

(2) The data is garbled.

a. If the output data is standard English characters, please confirm whether the computer keyboard is also in the US input method state.

b. If you use other computer keyboards to input, please set the scanner to the same keyboard language as the computer system.


After read this article, did you know the reason why you cannot use the wireless barcode scanner and find the solution? If haven't, please contact the seller to get the detailed solution.


Hope our barcode scanner can help you to work more effectively. And we will keep update many new CMOS barcode scanner with good quality and excellent reading performance.
