What is FM Transmitter
The FM Transmitter is a hand-held gadget, which can transform audio signal,
such as audio output of portable devices, into FM signals of three bands. It is very
suitable for users to listen to the un-upgradeable FM receiver-bundled stereo,
which cannot be connected to the music source through audio signal cable or
even has no audio input. It is also fit for those car owners, which hardly upgrade
their stereo but are eager to approach the latest fashion electronic devices
(portable CD-type MP3 player, portable flash-type MP3 player). Just turn on
radio to enjoy the favorite music without any difficulty.
How to Listen to Favorite Music
1. Load 2 x AAA batteries, ensuring that they are the correct way around
2. Connect the audio cable to the audio output of source device.
3. Power on the FM transmitter and source device. Then choose the frequency
by altering FM switch. (You can choose the following frequencies:
88.9,88.7,88.5 MHz)
4. Tune in your own FM receiver-bundled stereo or portable audio player to the
corresponding frequency.
