Explanation:
1. Insert FM02 into the USB interface in the car, and the output voltage is 5V.
Use the M key of the multifunctional device to set the FM frequency band, then turn on the car radio, and adjust the FM frequency band of the radio to match that of FM02. . 3. FM02 has an automatic FM frequency memory function. Each time it is powered on, it defaults to the last used FM frequency.
After setting the FM frequency band, find the Bluetooth compatible pairing name FM02 in the Bluetooth compatible settings of the mobile phone, and click to pair. Then the music played by the mobile phone will be played on the car's speakers.
5. Adjust the volume: When playing music, you can turn the music volume of the mobile phone to the maximum.
Adjust the car volume to a moderate level. It is not recommended to set the car volume too high, because the higher the car volume, the more severe the noise and distortion will be. 
Note:
1. The default frequency band of FM02 is 95.0 MHz and can be used directly. If there is a lot of noise during playback, you can adjust to another frequency band.
2. When the radio of certain vehicle models is turned on, the built-in USB interface in the vehicle will be turned off. At this time, if FM02 is inserted into the built-in USB port, it will not be usable. In this case, you can insert FM02 into the USB port of the ligter and the in-car charger. Use the power supply on the interface (the output voltage of the USB must be 5V).
3. FM02 may be too noisy or not usable in some original vehicles with USB interfaces. It is recommended to insert FM02 into the cirette ligter and in-car charger for use.
4. FM02 does not have an automatic shutdown function. It is recommended to unplug it from the USB interface when not in use.
5. When FM02 cannot be found in the Bluetooth-compatible settings of the mobile phone, or cannot be paired after clicking the search, it is recommended to clear the previously connected Bluetooth-compatible devices in the mobile phone and then restart the phone to try again.
