Setup Instructions
Follow these steps to set up your AINOPE Bluetooth FM Transmitter and connect it to your car's audio system.
Step 1: Find a Blank FM Frequency
Locate a "blank" or unused FM frequency on your car radio, typically between 88.1-107.9 MHz. A blank frequency will have no working radio station and will produce a slight rustle or white noise. This ensures optimal sound quality without interference.

Step 2: Adjust FM Transmitter Frequency
Plug the FM transmitter into your car's cigarette lighter socket. Long press the "/CH" button on the transmitter to enter frequency adjustment mode. Use the joystick controller to adjust the transmitter's frequency to match the blank frequency you found on your car radio. Once synced, the sound from the transmitter should be very quiet, indicating a clear connection.

Step 3: Pair Your Phone with the FM Transmitter
Enable Bluetooth on your mobile phone. Search for available Bluetooth devices and select "AV849" (or similar model name) to pair. If prompted for a PIN, enter "0000". Once paired, you can stream audio from your phone to your car's speakers via the FM transmitter.

Operating Instructions
Adjusting Volume
To adjust the audio volume, first increase the volume on your phone. If the volume is still too low, then adjust the volume on the FM transmitter using the joystick controller, and finally, adjust the volume on your car's speaker system. This three-step process ensures optimal sound output.

The transmitter also supports smart voice navigation from your phone, streaming audio from navigation apps, Siri, or Google Assistant directly to your car's speakers, enhancing driving safety.
