Connect the FM02 to the car's USB port with a 5V output. 2. Set the FM frequency band using the multifunction button M, then turn on the car radio and adjust the radio's FM frequency band to match that of the FM02. 3. The FM02 has an automatic FM frequency memory function; each time it is turned on, it will default to the last used FM frequency. 4. Once the FM frequency band is set, search for the Bluetooth pairing name: FM02 in your phone's Bluetooth settings and tap it to pair. Music played from your phone will then be played through your car speakers. 5. Volume Adjustment: When listening to music, you can set your phone's volume to maximum and your car radio's volume to a moderate level. It is not recommended to turn the car radio's volume up too high, as this may cause static and distortion. Precautions: 1. The FM02's default frequency band is 95 MHz and can be used directly. If significant static occurs during playback, it can be set to a different frequency band. 2. On some models, the vehicle's built-in USB interface is disabled when the car radio is turned on. In this case, if the FM02 is connected to the built-in USB port, it will not work. It is then possible to connect the FM02 to the cigarette lighter socket or a car charger. Power is then supplied via the interface (the USB output voltage must be 5V). 3. The FM02 is used in some vehicles equipped with factory-installed USB interfaces, which may be too noisy or unusable. It is recommended to connect the FM02 to a cigarette lighter socket charger for use. 4. The FM02 does not have an automatic shut-off function; it is recommended to disconnect it from the USB interface when not in use. 5. If the FM02 cannot be found in the mobile phone's Bluetooth settings or cannot be paired after being searched for and clicked, it is recommended to delete previously connected Bluetooth devices from the mobile phone, then restart the mobile phone and try again.
