1) Place the batteries in the battery compartment and turn the controller on.
2) Press the wireless button on top of the controller which will put the controller into pairing mode.
3) Make sure Bluetooth is enabled on your device, and the Stratus should then show up in the available devices menu. If the controller does not show up right away, try toggling the Bluetooth connectivity on and off on your device. This varies by device so if you are having trouble accessing the Bluetooth menu, we recommend referring to documentation for the device you're using with the Stratus XL.
