4. Compatibility Check
Before installing the HH671K-2.4G receiver, it is crucial to verify its compatibility with your child's electric vehicle. Follow these steps:
- Locate the Existing Control Box: Open the electric vehicle to access its current control box or receiver.
- Visual Comparison: Compare the appearance and connector layout of your existing control box with the CRIDENG HH671K-2.4G receiver. If they look identical in shape, size, and connector configuration, the HH671K-2.4G is likely compatible.
- Check Specifications: Ensure your vehicle operates on a 12V system, as this receiver is designed for 12V applications.
Note: Compatibility is primarily determined by visual matching of the control box and voltage requirements. If unsure, consult the vehicle's original manual or a qualified technician.

5. Installation and Pairing
5.1. Installation
Once compatibility is confirmed, proceed with the physical installation:
- Disconnect Power: Ensure the electric vehicle's battery is disconnected before beginning installation.
- Remove Old Receiver (if applicable): Carefully disconnect all wires from the old receiver and remove it from the vehicle.
- Connect New Receiver: Connect the wires from the vehicle to the corresponding ports on the HH671K-2.4G receiver. Pay close attention to polarity (positive/negative) and ensure all connections are firm.
- Secure Receiver: Mount the new receiver securely within the vehicle's housing to prevent movement during operation.
- Reconnect Power: Reconnect the vehicle's battery.
5.2. Pairing with Remote Control
To establish a connection between the receiver and a compatible 2.4G remote control:
- Power On Vehicle: Turn on the electric vehicle.
- Initiate Pairing on Remote: On the remote control, simultaneously press and hold the forward and reverse buttons. The indicator light on the remote control should begin to flash.
- Start Vehicle: While the remote's indicator light is flashing, start the electric vehicle (e.g., by pressing the power button on the vehicle).
- Confirm Connection: The indicator light on the remote control should stop flashing, indicating a successful connection. Test the remote control functions (forward, reverse, steering) to confirm pairing.
If pairing fails, repeat the steps. Ensure the remote control has fresh batteries.
6. Operation
6.1. Slow Start Function
The HH671K-2.4G receiver features a built-in slow start function. This means that when the vehicle is commanded to move (either via pedal or remote control), it will gradually increase speed rather than accelerating abruptly. This provides a smoother and safer experience for the child, reducing sudden jerks.
- No additional slow starter components are required.
- The slow start function is automatically active once the receiver is correctly installed and paired.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Vehicle does not respond to remote control. | Not paired, remote control batteries low/dead, incorrect wiring. | Re-attempt pairing (Section 5.2). Replace remote control batteries. Check all wiring connections. |
| Vehicle does not move or moves intermittently. | Loose wiring, low vehicle battery, motor issue, receiver malfunction. | Check all wiring connections. Charge vehicle battery. Consult a technician if motor or receiver is suspected faulty. |
| Slow start function not working. | Receiver malfunction. | Ensure receiver is correctly installed. If issue persists, the receiver may be faulty and require replacement. |
