1. Introduction
This manual provides comprehensive instructions for the installation, operation, and maintenance of the Manlos Children's Electric Car Receiver and Remote Control System. This system is designed to provide reliable control for compatible children's electric vehicles. Please read this manual thoroughly before installation and use to ensure proper function and safety.
2. Safety Information
Always observe the following safety precautions to prevent injury or damage to the product:
- Ensure the electric car's power is OFF before installing or removing any components.
- Only use this product with compatible children's electric cars and power sources (DC 12V).
- Do not expose the receiver or remote control to water, moisture, or extreme temperatures.
- Keep small parts and batteries out of reach of young children to prevent choking hazards.
- If any component is damaged, discontinue use immediately and replace it with an original part.
- Installation should be performed by an adult or under adult supervision.
3. Product Overview
The system consists of a receiver unit (circuit board/motherboard) and a remote control. Different models of receivers may be compatible with the same remote control system.

This image displays the HH-6188K-2.4G receiver, a black rectangular circuit board with a label indicating "HH-6188K-2.4G", "Voltage: DC 12V", and "Load current: 20A". It features multiple connection ports for wiring.

This image shows the beige-colored 619Y remote control. It has several black buttons, including directional arrows, and two larger circular buttons, resembling a game controller.

This image presents both the HH-670K-2.4G receiver and the 619Y remote control. The receiver is similar in appearance to the HH-6188K model, and the remote control is the same beige unit. This illustrates the complete system.
4. Setup and Installation
Follow these steps to install the receiver and pair the remote control:
- Power Disconnection: Ensure the children's electric car is completely powered off and disconnected from its power source before beginning installation.
- Locate Receiver Compartment: Identify the designated compartment for the receiver unit within the electric car. This is typically under the seat or hood.
- Connect Wiring: Carefully connect the wiring harness from the electric car to the corresponding ports on the HH-6188K-2.4G or HH-670K-2.4G receiver. Refer to the electric car's original wiring diagram if available. Ensure all connections are secure and correctly polarized.
- Secure Receiver: Mount the receiver securely within its compartment using appropriate fasteners (not included) to prevent movement during operation.
- Install Remote Batteries: Open the battery compartment on the back of the 619Y remote control and insert the required batteries (typically AAA, not included), observing correct polarity.
- Pairing Procedure:
- Turn on the electric car's power.
- Within 5 seconds of turning on the car, press and hold the "M" or "Code" button on the 619Y remote control until the indicator light on the remote or receiver flashes.
- Release the button. The light should stop flashing and remain solid, indicating successful pairing.
- Test the remote control functions (forward, backward, turn) to confirm pairing.
5. Operating Instructions
Once the receiver and remote control are successfully paired, you can operate the electric car using the 619Y remote control:
- Power On/Off: Use the main power switch on the electric car to turn it on or off. The remote control will only function when the car is powered on.
- Forward/Backward: Use the designated joystick or directional buttons on the remote to move the car forward or backward.
- Turning: Use the left/right directional buttons to steer the car.
- Speed Control (if applicable): Some remote controls may have buttons to adjust the speed settings (e.g., high/low speed). Refer to your specific remote's markings.
- Emergency Stop (if applicable): If your remote has an emergency stop button, pressing it will immediately halt the vehicle.
Always supervise children during operation and ensure they are in a safe environment free from obstacles.
6. Maintenance
Proper maintenance ensures the longevity and reliable performance of your receiver and remote control system:
- Cleaning: Wipe the receiver and remote control with a soft, dry cloth. Do not use harsh chemicals or abrasive cleaners.
- Battery Replacement: Replace the remote control batteries when the indicator light dims or the remote's range decreases. Always use new batteries of the specified type. Dispose of old batteries responsibly.
- Storage: When not in use for extended periods, remove batteries from the remote control and store both the receiver (within the car) and remote in a cool, dry place away from direct sunlight.
- Connection Check: Periodically inspect all wiring connections to the receiver to ensure they remain secure and free from corrosion.
