It is recommended that Spark 4K devices be set to the region that they are currently operating in to comply with the local allowed frequencies. You will need to use the Launchpad Desktop App.
Let's Get Started
First, connect either the Spark 4K transmitter or receiver to your computer via the USB-C port. The receiver cannot be powered by the computer’s USB port alone and needs to be powered by the included 12v DC barrel adapter.
Launch Launchpad on your computer. The currently connected Spark device will show up under Device Type.
Click on the Settings tab and click Select Region…
Choose your region in the dropdown menu and then click Okay.
Your Spark 4K device’s region will be changed and your device will restart.
