Billboard volume???

Hi, I’m sure this is an easy fix that I am missing, but how do you get rid of the music on the metro liner billboard? I wasn’t aware it played music when you turned it on and can’t figure out how to turn the music off. Thank you!

  • Hi, thanks for your message.  That's not actually music, though it can sound like it.  That's the sound of the voltage transformer inside the power supply converting the battery voltage to the high voltage required by the billboard.  This is an artifact of any electroluminescent product, whether it be EL wire, EL masks, EL Halloween costumes, etc.  Unfortunately it's part of the technology and cannot be turned off.
