## Problems And Solutions

1. If host communication is used, pop-up error prompts, such as communication error, unable to obtain communication address and unable to obtain interactive address, are generally caused by the radio not responding and not replying. You need to press the device side button or restart the device to activate the device.

2. If it doesn't work after trying, please check whether the data cable is connected correctly and whether the device is turned on. After confirming the above situation is correct, then perform other solutions: restart the device and plug the data cable by forcibly powering off the hardware by removing the battery.
