Dimensions approx: 90.8x50.5x20.3(mm). FM-01 FUNCTION: Transmit the output audio signals of CD/VCD to the wireless sending audio wave at the preestablished frequency. The receivers will receive the audio signals with the accordance to the same frequency. USEAGE: The output wireless frequency can be adjusted by the frequency switch on the product. Turn on the receiver and adjust to the proper frequency receiving mode, then it can be use to receive the audio signals from CD/VCD. Eg, If the frequency switch is set to 88.1MHZ, the sound wave output will be the same. PARAMETER Modulated Frequency: 88.1 88.3 88.5 88.7 88.9MHZ. DV input:12V Input: Stereo Output: FM output.
