<p>Ⅱ. Update your AIRSTEP’s firmware with AIRSTEP Updater, and update your AIRSTEP App.</p>
<p>Ⅲ. After the firmware update, AIRSTEP will automatically pair the THR II nearby. After the successful connection, the connection indicator will be solid green(At the same time, the connection indicator also shows the number of connected smart devices, so the status of the indicator may be green/green with blue blinking/blue-green, depending on how many smart devices are connected to AIRSTEP). You can only connect one device of THR II/Spark Amp/KATANA-AIR/WAZA-AIR at the same time.</p>
