General Operation
This is a medium-powered device that can pick up conversations and sounds within a 10 meter radius and transmit them to a dedicated VHF receiver or FM radio to a distance of up to 600 meters with good clarity. It is extremely simple to operate. Connect the battery, tune a AM/FM Radio to somewhere between 88 and 92 MHz (play some music or make noise so when you tune the correct frequency you recognize the audio) and you’re away!
