These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:
622 +== 3.9  Upgrade Firmware of LA66 USB LoRaWAN Adapter ==
473 473  
474 -—Reorient or relocate the receiving antenna.
624 +The LA66 USB LoRaWAN Adapter is the same as the LA66 LoRaWAN Shield update method
475 475  
476 -—Increase the separation between the equipment and receiver.
626 +Just use the yellow jumper cap to short the BOOT corner and the RX corner, and then press the RESET button (without the jumper cap, you can directly short the BOOT corner and the RX corner with a wire to achieve the same effect)
