4. Operating Instructions
4.1. Multi-Platform Switching
The controller features a dedicated button to switch between supported platforms. Locate the platform switch button on the back of the controller (labeled S/B/NS/APP) and press it to cycle through modes for PC (S), Bluetooth (B), Nintendo Switch (NS), or App (APP) for customization.
4.2. TMR Joysticks and Adjustable Tension
The TMR joysticks offer adjustable tension. To modify the tension, gently rotate the ring at the base of each joystick. Rotating counter-clockwise will decrease tension (30gf) for quicker, more agile movements, while rotating clockwise will increase tension (90gf) for improved aiming precision.
4.3. TMR Triggers
The TMR triggers provide precise and responsive input. They can operate in two modes:
- Micro-Switch Trigger: For ultra-fast response, ideal for shooting games.
- Analog Linear Trigger: For pressure-sensitive action, suitable for racing games.
Trigger modes can be adjusted via the BEITONG Gamepad Assistant software.
4.4. Optical Buttons and Hybrid D-Pad
The optical buttons provide rapid and smooth feedback. The Hybrid D-Pad offers enhanced directional accuracy. These features are designed to improve response time and control in various game genres.
4.5. 6-Axis Gyro Motion Control
The built-in 6-axis gyroscope enables motion control functionality in compatible games. This allows for intuitive aiming and movement based on the controller's orientation.

4.6. Turbo Function
Activate the Turbo function by pressing the "Turbo" button followed by the desired action button. This allows for rapid, repeated input of that button, simplifying combos or continuous actions. Press the "Turbo" button again with the same action button to deactivate.
4.7. Programmable Back Paddles (M1, M2)
The two back paddles (M1 and M2) can be programmed to replicate any other button on the controller. This allows for quick access to frequently used commands without repositioning your thumbs.
