   On your car radio, select an unused FM frequency (a blank channel with no strong broadcast). Press the "CH" button on the transmitter, then rotate the ring knob to adjust the transmitter's frequency to match your car radio's frequency. This is crucial for clear audio transmission.

3. Step 3: Pair with Bluetooth
   Enable Bluetooth on your smartphone. Search for "SW-XC653" in the list of available devices and select it to pair. Once paired, the LED display will show a steady "bt" and you will hear a confirmation tone.
