8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Boat does not respond to transmitter. | Low battery in boat or transmitter; Not paired; Out of range. | Charge boat battery; Replace transmitter batteries; Re-pair boat and transmitter; Operate within range (400ft). |
| Boat runs slowly or intermittently. | Low boat battery; Propeller tangled with debris; Motor overheating. | Charge boat battery; Clear propeller; Allow motor to cool down. |
| Boat capsizes frequently. | Operating in rough water; High speed turns. | Operate in calmer water; Reduce speed during turns. The self-righting function should correct it. |
| Water inside the boat. | Hatches not sealed properly; Damage to hull. | Ensure all hatches are securely closed before use; Inspect hull for cracks and repair if necessary. |
