FM MODULATOR If your car stereo system do not have RCA input jack, use the FM Modulator to convert DVD’s sound to RF output signal that can be received by the FM TUNER of your system, so you can hear it by tuning your vehicle system to an FM frequency.
4. OUTPUT FREQUENCY CONVERTING: Turn the switch (4) on the side of the FM Modulator to choose the FM Modulator’s RF output frequency between 88.5 MHz and 88.9 MHz with a screwdriver. When the reception is inter- fered with other station on the one frequency, switch to the another frequency.
