  1. How can I install the FM Transmitter

    1. Install the antenna;

    2. Link the cable to the antenna;

    3. Link the 50 Ohm Coax cable to the "ANT"-(BNC Type)Be sure the link is stable;

    4. Link the audio input to the "Audio"-3.5MM Stereo socket;

    5. Link the DC POWER module to the "POWER"¨C6.5mm POWER socket ( DC 12V(current >2A) Pay Attention to the power polar : inside positive; outside negative);

    6. After electrified,the frequency is the one of last power off;

    7. Frequency Increase Control, pull the button"UP", every pull can increase 100KHz,pull the button for more than 1 second,the stepping jump to 1MHz;

    8. Frequency Decrease Control,pull the button"DOWN", every pull can decrease 100KHz,pull the button for more than 1 second,the stepping jump to 1MHz.

  10. Why Doesn't My FM Transmitter Turn On?
    • Is the power cord firmly attached to the FM transmitter?
    • Is the AC adapter plugged into the wall?
    • Make sure the audio cable is firmly plugged into both devices.
    • make sure the volume is not all the way down.
    • Make sure your audio device is working.

  11. Why Don't I Hear Anything?
    • Is the audio cable firmly attached to the  FM Transmitter  and your audio source?
    • Is the volume turned up on your audio source?
    • Is the volume turned up on your FM Receiver source?
    • Make sure the audio cable is firmly plugged into both devices.
    • Make sure your audio device is working.

  12. I Think All Of The FM Frequencies Are Used In My Area?
    Some people report that all transmitter channels are being used. This is not possible since the FCC requires blank channels between commercial stations. What they are hearing is bleed-over noise from a commercial station. When you select one of these blank channels the FM transmitter will broadcast over the noise.

  13. I Lost My AC Adapter Can I Use Some Other One?
    Yes, you can use the appropriate +12 V switching power supply. Must pay attention to the polarity of power.
