be affected even in places subject to extreme change in temperature; in addition,
using the digital tune can avoid the fussy frequency modulation
3) Powered by batteries or the car's power source
4) Full frequency range design can effectively avoid interruption
Operation instruction:
1) Install the batteries (2 AAA batteries) or connect to the car's power source
2) Plug the FM Transmitter into the audio device's output port
3) Adjust the volume and frequency of the FM radio (avoid the transmission points

according to the reception frequency of the FM radio (if the FM signal is interrupted,
please set the frequency of the FM transmitter and the FM tuner to the other
frequency)
5) Press M1/M2/M3/M4 button for a few seconds until M1/M2/M3/M4 is shown on the LCD,
so that you can save the transmission frequency (make sure the batteries have
power)
