4. Operating Instructions
4.1. Basic Controls (2.4G Handle Remote Control)

- Forward/Retreat: Use the left joystick to move the car forward or backward.
- Left/Right Rotation: Use the right joystick to rotate the car left or right.
- Combined Movement:
- Forward/Backward + Left Rotation = Forward/Backward Left Turn
- Forward/Backward + Right Rotation = Forward/Backward Right Turn
- Water Spray: Short press the dedicated button (usually labeled with a water icon) to activate water spraying.
- Lights On/Off: Long press the dedicated button (usually labeled with a water icon) to turn the LED lights on or off.
- Automatic Demonstration: Short press the dedicated button (usually labeled with a water icon) to activate an automatic demonstration mode.

4.2. Amphibious Operation
The JCMO RC Water Gun Car is designed for both land and water use.
- On Land: Operate the car on various terrains like grass, gravel, or pavement.
- In Water: The vehicle is fully waterproof. Drive it into shallow water (pools, puddles) for aquatic fun. The wheels are designed for propulsion in water.


4.3. Automatic Water Absorption
For continuous water spraying in water, the car features automatic water absorption.
- When the car is in water, locate the water intake cover on the bottom of the vehicle.
- Unclip or open this cover. The car will then automatically absorb water to refill its internal tank for spraying.
- Ensure the cover is securely closed when operating on land or when not using the automatic absorption feature.

4.4. Special Maneuvers
- Standing Drive: The car can perform a unique two-wheel standing drive. After retreating, advancing can enter standing mode. In standing mode, it can move forward and rotate 360 degrees.
- 360° Rotation: The car is capable of full 360-degree rotations, allowing for dynamic turns and stunts.
