4. Multiple protection functions: Overvoltage protection, undervoltage protection, overtemperature protection, stall protection, overcurrent protection

Key Features of the W300 Remote Control:
(1) Water resistance: 1 meter
(2) Cruise control function
(3) Controls two thrusters to move forward, backward, and turn left or right
(4) During straight-line navigation, automatically corrects any deviation in course to maintain a continuous straight path
(5) Optional GPS module enables waypoint functionality and position holding against currents or headwinds

Note (W300 remote control version): Place the white (or black) sealed housing flat during operation. It contains a gyroscope that automatically corrects the course for straight-line navigation; if the unit is not positioned horizontally, the thrusters may malfunction.
