Note:
In normal use, please adjust it to an unused frequency.
If the noise is too loud, try another FM frequency.
This is normal, any FM transmitter signals are sometimes surrounded by a radio frequency signal or similar interference, causing noise.
This is normal, it may interfere with the FM signal, noise and lead to a number of currencies, if nearby substation.
Please use the telephone microphone to speak, because the transmitter does not have a microphone.
It differs transmitter maximum output current and the charging equipment, as the charging device can automatically limit the output current. Input current with different equipment and different charge, low power, greater investment.
