User manual

Do not use the pulse headphones while operating machinery or motor vehicles as the pulse will
impair your ability to hear important safety signals and therefore present a danger to you and
others. We also ask that you please be considerate to others when listening to your music in
places like libraries or on public transit. Finally, even if you are an Electrical Engineer, please do not
attempt to repair, disassemble or modify the pulse in any way.
