Why
AFC (Automatic Frequency Change) function is
essential
The CA500 is equipped with a smart FM
transmitter. Our smart FM transmitter
component comes with a unique AFC technology
(patent pending) that finds the clearest
available FM transmitting frequency for our
FM transmitter then forces your car radio to
tune to the same frequency automatically
without you bothering 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.
