To reset the IR blaster, first you need to unregister the device from your account.
After unregistering, to fully reset the device, press and hold the IB button for 10 to 15 seconds.
By pressing and holding the button, the Wi-Fi network will be completely forgotten which will allow you to set up the device again.
It is no necessary to unregister the device if the same user ID is using the same device again.
