The transmitter features two operational modes: A Mode (for setting) and B Mode (Standard operation). You can adjust steering trim, throttle trim, and reverse servo/motor direction. The LED key controls light effects: one press for headlights, two for full power, three for headlights and blackout lamp. The button below the LED activates turn lights, which flash when turning the wheel. The ST Angle button sets steering range (30%, 50%, 100%). The Train button limits throttle output to 50% for precise control on rough terrain. The Climbing button activates climbing mode, engaging the brake to prevent backward movement on inclines.

4. Operating

4.1 Driving Modes

The vehicle offers two primary driving modes: Crawling Mode and Beginner Mode. These can be selected via the 2.4GHz ANT transmitter. Crawling Mode provides precise, low-speed control ideal for navigating challenging obstacles and rough terrain. Beginner Mode offers a more forgiving and stable driving experience, suitable for new users or general recreational driving.

4.2 Light Controls

The integrated LED system includes headlights, turn lights, and a blackout lamp. These can be controlled directly from the transmitter. Headlights can be activated for low-light conditions, and turn lights will illuminate when steering, enhancing realism and visibility.

4.3 Gear Shift

The two-speed transmission allows for shifting between different gear ratios to optimize performance for various driving conditions. Use the shift function on the transmitter to switch between gears, providing either higher torque for climbing or higher speed for open terrain.

5. Maintenance

Regular maintenance is crucial for the longevity and optimal performance of your RC car. After each use, especially after driving in dirt, mud, or wet conditions, clean the vehicle thoroughly. Remove any debris from the chassis, suspension components, and wheels. Inspect all moving parts for wear and tear, including gears, driveshafts, and suspension links. Ensure all screws are tight. Lubricate moving parts as recommended in the detailed product manual (if applicable). Store the vehicle and battery in a cool, dry place away from direct sunlight and extreme temperatures.

6. Troubleshooting

6.1 No Power

• Ensure the vehicle's battery is fully charged and properly connected.
