Why AFC (Automatic Frequency Change) function is essential

AFC resolves conventional FM transmitter¡¦s deficiency and lets you listen

to clear external audio thru in-car radio, wirelessly and totally hands free


The AD350 is equipped with a smart FM transmitter which comes with an unique AFC technology (patent pending) that detects frequency interference, finds the clearest available FM transmitting frequency for our FM transmitter, and then forces your car radio totune to the same frequency automatically without bothering you to touch any buttons, completely hands-free.


If you want to drive and listen to DAB or the music playing by smartphone/MP3 player through your car radio wirelessly, you will need a FM transmitter.  However, while you are driving, the audio output will become distorted anytime the FM transmitter¡¦s frequency is being interfered with.  For FM transmitter without AFC, you will need to do the following manually in order to continue to listen to the clear audio:

1. Find an unused FM frequency by tuning your car radio.

2. Change FM transmitter to use the same unused frequency.

3. Repeat above steps each time the audio output becomes distorted.


Thus, this can be hazardous and inconvenient for the driver.  With our smart FM transmitter, you don¡¦t have to do anything and the audio output is always clear.  AFC continuously detects the quality of signal reception and each time it finds the frequency is being interfered with, it does the frequency change automatically for you.
