Introduction
This manual provides essential instructions for the installation, operation, and maintenance of your weelye RX19 12V Bluetooth Receiver Controller. This control box is designed as a replacement part for children's electric ride-on cars, featuring a 2.4G Bluetooth receiver and a slow start function for enhanced safety and control.
Compatibility Check
Before installation, it is crucial to verify that the RX19 control box is compatible with your specific ride-on car model. To ensure compatibility:
- Open the broken electric ride-on car and locate the existing control box.
- Compare the appearance of the existing control box with the weelye RX19. If the physical appearance, including connectors and dimensions, is identical, this part should be compatible with your car.
- Additionally, confirm that other essential functions of your car, such as motors and batteries, are in proper working condition.

Setup and Frequency Matching
For the first use, or after replacing the battery in the remote control, the receiver needs to be paired with the remote control. Follow these steps for frequency matching:
- Install Batteries in Remote Control: Install two AAA 1.5V batteries into the remote control. Ensure correct positive and negative polarity inside the battery chamber. Close the battery cover. The indicator light on the remote will flash three times, confirming correct battery installation.
- Activate Pairing Mode on Remote: Press and hold the frequency key (often labeled "car select" or a similar pairing icon) on the remote control for approximately 2 seconds. The indicator light on the remote will begin to flash, indicating it is in pairing mode.
- Power On the Ride-On Car: Turn on the main power supply of the electric ride-on car. The indicator light on the remote control should turn off, signifying a successful frequency match.
- Troubleshooting Unsuccessful Match: If the indicator light on the remote does not turn off, the frequency matching was unsuccessful. Turn off the power supply of the car and repeat steps 2 and 3 until successful.
