2. Installing Batteries in the Remote Controller
The remote controller requires 4x AA batteries (not included). Open the battery compartment on the back of the remote and insert the batteries, observing correct polarity.
3. Installing the Loader Battery
- Locate the battery compartment on the RC loader (refer to Figure 6 for general location).
- Carefully connect the charged battery to the loader's power connector.
- Secure the battery within the compartment and close the cover.
4. Pairing the Remote Controller
- Ensure both the loader and the remote controller are powered off.
- Turn on the RC loader.
- Turn on the remote controller. The remote and loader should automatically pair. A successful connection is usually indicated by a solid light on both devices.
- If pairing fails, turn both devices off and repeat the process.
Operating Instructions
