How can I avoid or reduce noise?

For best sound quality, set the car audio volume below 50% before connecting your phone. Then, connect to the FM frequency & Bluetooth. Adjust the phone & BC91 volume first. If it's still too low, adjust the car audio system to reach the ideal level.

How do I match & switch frequencies?

Turn on car radio to blank FM frequency. Set the BC91 to the same frequency as the car radio. Long-press the BC91 rotate button until frequency flashes. Turn clockwise to increase, counter-clockwise to decrease.

The device isn't working/power isn't responding/display isn't showing/car audio isn't receiving sound/unable to play?

1) Ensure that the FM transmitter is on.

How to pair the FM transmitter with your phone via Bluetooth?

Plug BC91 into car cigarette lighter socket to power on. Enable your phone's Bluetooth is on. Then search for 'BC91 and select 'connect'. Once connected, you can start playing music, using navigation, or making hands-free calls.
