Any station is fine as long as it is not in used (no broadcast). 2. Pair Frequency: Make sure the channel on the transmitter and the channel on the radio are the same. 3. Adjust Volume: If you feel the sound is low, please increase the volume of your phone. You can set your phone volume to maximum.
