ASBDA01 and ASBPB01 Listening Device User Guide
These listening devices can pick up conversations and sounds within a 10-15 metre radius and transmit them to a dedicated VHF receiver or FM radio to a distance of up to 100 metres with good clarity. It is extremely simple to setup. Connect to power, tune a AM/FM Radio to somewhere between 88 and 95 MHz (play some music or make noise so when you tune the correct frequency you recognize the audio) and you’re away! No maintenance is required as these listening devices come fully assembled ready to plug in and transmit.
They are also a functioning power board and double adapter so you can power other devices.
