5. Setup
5.1 Battery Installation and Charging
- Vehicle Battery: The MN82S includes two 7.4V 1200mAh rechargeable batteries. Connect one battery to the vehicle's battery connector. Ensure the connection is secure.
- Charging: Use the provided USB charging cable to charge the batteries. Connect the battery to the USB cable, then plug the USB cable into a suitable USB power source (e.g., computer USB port, USB wall adapter). The charging indicator will show the charging status. A full charge typically takes approximately 30 minutes of playtime per battery.
- Remote Control Battery: Install 1 AA battery (included) into the remote control transmitter. Observe correct polarity.
5.2 Remote Control Pairing
The 2.4GHz remote control system offers excellent anti-interference performance. Follow these steps to pair the remote control with the vehicle:
- Ensure both the vehicle and the remote control are powered off.
- Turn on the vehicle. The vehicle's indicator light may flash.
- Turn on the remote control. The remote control's indicator light should also flash.
- Wait for a few seconds. The indicator lights on both the vehicle and the remote control should become solid, indicating a successful pairing.
- If pairing fails, turn off both devices and repeat the process.
