- Battery Safety: Use only the provided batteries and charger. Do not overcharge or short-circuit batteries. Remove batteries from the boat and remote when not in use.
- Propeller Warning: Keep fingers, hair, and loose clothing away from the propeller when the boat is powered on.
- Water Sensing Feature: The boat's motor will only activate when it is placed in water, preventing accidental propeller rotation out of water.
- Temperature: Avoid operating in extreme temperatures.
4. Setup
4.1 Charging the Boat Battery
- Connect the USB charging cable to the boat battery.
- Plug the USB cable into a compatible USB power adapter (not included).
- The indicator light on the USB cable will show charging status (e.g., red for charging, off for fully charged).
- Charging typically takes 2-3 hours. Do not leave unattended during charging.
4.2 Installing Batteries in the Remote Controller
- Open the battery compartment on the back of the remote controller.
- Insert 2 x AA batteries (not included), ensuring correct polarity (+/-).
- Close the battery compartment securely.
4.3 Installing the Boat Battery
- Open the top hatch of the boat.
- Connect the fully charged battery to the boat's power connector.
- Carefully place the battery inside the compartment.
- Ensure the waterproof seal is properly seated and close the hatch securely to prevent water ingress.
5. Operating Instructions
5.1 Power On and Pairing
- Turn on the remote controller. The indicator light will flash.
- Place the boat gently into the water. The boat's LED lights will activate, and the motor will be ready.
- The remote controller and boat will automatically pair. The remote's indicator light will become solid when paired.

5.2 Controls
- Throttle (Left Stick/Trigger): Push forward to accelerate, pull back to reverse. The boat features fully proportional throttle for precise speed control.
- Steering (Right Stick/Wheel): Turn left or right to steer the boat. Fully proportional steering allows for smooth turns.
- LED Lights: The boat features dynamic LED lights for enhanced visibility and aesthetics, especially during evening operation.
5.3 Capsize Recovery
If the boat flips over during operation, use the remote control to activate the capsize recovery function. Typically, this involves pushing the throttle stick forward and then quickly pulling it back, or a specific button combination, to right the boat automatically.

5.4 Low Battery and Weak Signal Alarms
- Low Battery: The remote controller will emit an audible alarm (beeping) when the boat's battery is low. Return the boat to shore immediately to avoid losing control.
- Weak Signal: If the boat moves out of range (approximately 197 feet or 60 meters), the remote controller will alert you with a weak signal alarm. Bring the boat closer to regain full control.

6. Maintenance
- Cleaning: After each use, wipe the boat clean with a soft, dry cloth. Ensure no debris is caught in the propeller or rudder.
- Drying: Open the boat's hatch and allow the interior to air dry completely before storage. This prevents moisture buildup and potential damage to electronics.
- Battery Care: Store batteries in a cool, dry place. Do not store fully charged or completely depleted for extended periods. Charge them to about 50% for long-term storage.
- Propeller Inspection: Regularly check the propeller for damage or entanglement. Replace with the spare propeller if necessary.
- Water Circulation Cooling: The boat features a water circulation cooling system for the motor. Ensure the water intake and outlet are clear of obstructions.
