Operating Instructions
1. Powering On and Pairing

2. Basic Controls
The LHD-881 boat supports the following movements:
- Forward: Push the throttle stick/button forward.
- Backward: Pull the throttle stick/button backward.
- Turn Left: Move the steering stick/button to the left.
- Turn Right: Move the steering stick/button to the right.

- Watch Remote Controller: The green light will remain steadily lit.
When the low battery alarm activates, return the boat to shore immediately to avoid losing power in the water.
4. Water Outage Safety Feature
The boat is equipped with an intelligent sensor that automatically powers off the hull when it leaves the water surface. This prevents accidental propeller operation out of water.
