Description

UHF FM audio transmitter for UHF FM spy micro earpiece receiver

The new thing of this transmitter is that it works with audio input from many devices like TV, radio, MP3 player, Ipod, mobile phone, walkie-talkie, walkman, etc. That’s why we called
it a FM audio transmitter.

What is it for:
The audio FM transmitter, connected to an audio device, together with the spy in-ear UHF receiver, can be used as a source of information or as a hidden music player or just as a hidden prompter while you make a presentation.

How it works:
The audio signal from the audio source is put in the UHF FM transmitter and it will transmit a radio signal in the UHF frequency. The radio signal will be received by the special UHF
FM spy micro earpiece receiver MRF400-C in the range of a room, bus, etc. (~ 10 meters).
All you have to do is to connect it to the audio device using the jack input; put the battery into the spy micro earpiece UHF FM receiver and put it in your ear. You will be able to
listen and no one will notice anything.
