100% brand new high quality Weelye Kids Electric Toy Car Remote Control and Receiver 2.4G Bluetooth Transmitter. Bluetooth remote control instructions: 1. For first use or after battery replacement, frequency matching is required. Step 1: Install two AAA 1.5V batteries (observe correct polarity in the battery compartment), then close the battery cover. The indicator light will flash three times, indicating correct battery installation. Step 2: Press and hold the frequency key (car selection) for approximately 2 seconds until the indicator light flashes. Step 3: Turn on the car’s power; the indicator light will turn off. Step 4: If frequency matching fails (indicator light does not turn off), power off and repeat steps 2 and 3. How to choose remote control and receiver: 1. The remote controls have the same appearance and are universal. 2. For the receiver, check the side sticker marked RX… and select the matching model. 3.
