Safety Information
- Always ensure adult supervision when children are operating electric ride-on cars, especially when using the remote control.
- Verify that the electric car's voltage (6V or 12V) matches the receiver's compatibility before installation to prevent damage.
- Disconnect the electric car's power source before installing or replacing the receiver to avoid electrical hazards.
- Keep the remote control and receiver away from water, moisture, and extreme temperatures.
- Do not attempt to modify or disassemble the remote control or receiver, as this may void the warranty and cause malfunction.

Setup and Installation
Follow these steps to install the LB-RX 2.4G receiver and prepare the LB350 remote control for use:
- Prepare the Electric Car:
- Ensure the electric car is turned off and disconnected from its power source (battery).
- Locate the existing receiver or the designated area for the receiver within the electric car. This often requires opening a compartment or panel.
- If replacing an old receiver, carefully disconnect all wires from the old unit. Note the wiring configuration for proper connection of the new receiver.
- Install the LB-RX 2.4G Receiver:
- Connect the wires from the electric car (power, motor, steering, etc.) to the corresponding ports on the LB-RX 2.4G receiver. Refer to the car's original wiring diagram or the labels on the receiver for correct connections. The receiver supports 6V and 12V systems.
- Secure the receiver in a safe, dry location within the car, away from moving parts or excessive heat.

- Install Batteries in LB350 Remote Control:
- Open the battery compartment on the back of the LB350 remote control.
- Insert the required batteries (typically AA or AAA, not specified but common for remotes) according to the polarity markings (+/-).
- Close the battery compartment securely.

Operating Instructions
Once the receiver is installed and the remote has batteries, follow these steps to operate the electric car:
- Power On:
- Turn on the electric ride-on car using its main power switch.
- Turn on the LB350 remote control. An indicator light on the remote should illuminate.
- Pairing (if necessary):
For 2.4G systems, pairing is often required for the first use or after battery changes. If the car does not respond to the remote, follow these general pairing steps:
- Ensure the electric car is OFF.
- Press and hold the "Pairing" button on the remote control (if available, often a small recessed button or a combination of main buttons). If no specific pairing button is visible, try holding the "Forward" and "Backward" buttons simultaneously.
- While holding the button(s) on the remote, turn ON the electric car.
- Observe the indicator lights on both the remote and the receiver. They should flash during pairing and then become solid once successfully paired.
- Release the button(s) on the remote. The car should now be controllable.
- Controlling the Car:
The LB350 remote control features hexagonal buttons for directional control and small indicator lights. Common controls include:
- Forward/Backward: Use the designated buttons (often marked with arrows or symbols) to move the car forward or backward.
- Left/Right: Use the designated buttons to steer the car left or right.
- Stop: Releasing the directional buttons typically stops the car. Some remotes may have a dedicated stop button.
- Speed Selection: If available, the small dots on the remote may indicate speed settings (e.g., 1, 2, 3 for low, medium, high speed). Pressing these buttons will cycle through available speeds.

Maintenance
- Keep both the remote control and receiver clean by wiping them with a dry, soft cloth.
- Store the kit in a cool, dry place when not in use.
- If the remote control will not be used for an extended period, remove the batteries to prevent leakage.
- Periodically check all wire connections to the receiver to ensure they are secure.
