How to pair and use WHB04 Wireless Handwheel and USB receiver
Open the pairing software XHC-PHBX-内部测试-V1.2
As shown below, the software will prompt please insert USB reviver.

After inserting the receiver, if it prompts “PHBX job ok!”, it means that the receiver is successfully recognized by the computer. If there is no prompt, it means that the receiver is not recognized, please check.

After the receiver is correct, click the re-pairing button on the software, then turn on the power with the handwheel, press and hold the RESET button for 5 seconds, and then release it.
