583	583
584		-* **Before v1.6 firmware**: LDS02 works in Subband 2 by default in AU915 / US915 band. So if the LoRaWAN server works in other subband, there will be issue for LWL02 to Join the server. In this case, User can use AT COmmand to change the subband. See AT Command chapther for the hardware connection. Below are the steps to change sub-band:
585		-** Press rest button.
586		-** Send **123456** password
587		-** Send command **AT+CFREQBANDMASK=0001 **( 0001 for subband 1, 0002 for subband 2, etc..)
