2. Set FM Frequency:
   • Tune your car's FM radio to an unused frequency (one with no static or strong broadcast).
   • On the BC83, press the 'FM' button (or similar button indicated in the images) to enter FM tuning mode. Use the navigation buttons (e.g., 'M' and 'FM' buttons shown in images) to adjust the BC83's FM frequency to match your car's radio.
   • Ensure the frequencies match for optimal audio transmission.
3. Bluetooth Pairing:
   • The BC83 will automatically enter Bluetooth pairing mode when powered on.
   • On your smartphone, enable Bluetooth and search for available devices.
   • Select "BC83" (or similar name displayed on the device) from the list to pair. A voice prompt or display indicator will confirm successful pairing.
   • The device supports automatic reconnection to the last paired device.
4. Media Playback (Optional):
   • U Disk/TF Card: Insert a U disk or TF card (up to 32GB) containing WMA, MP3, WAV, APE, or FLAC audio files into the designated slot on the BC83. The device will automatically detect and play music from the storage.
   • AUX Mode: If your car has an AUX input, you can connect the BC83 to your car's AUX port using an audio cable for a direct wired connection. This bypasses FM transmission.
