Power the Game Stick: Connect the included USB power cable to the game stick and then to a USB power source (e.g., a USB port on your TV, a USB wall adapter). The game stick requires power to operate.
Insert Controller Batteries: Each wireless controller requires batteries (not included). Open the battery compartment on the back of each controller and insert the required batteries, ensuring correct polarity.
Select TV Input: Turn on your TV and use its remote control to select the correct HDMI input source where the game stick is connected. The game stick's menu should appear on the screen.
Controller Pairing/Selection: On the side of each controller, there is a switch labeled '1P' and '2P'. For single-player games, ensure one controller is set to '1P'. For two-player games, set one controller to '1P' and the other to '2P'. This avoids compatibility issues.
