1. Unbutton the silicone strap from the black button.
2. Wrap the strap around the object you want to hang the Power Amp 18 from, then pull the loop through the metal D-Ring.
NOTE: The silicone loop has a metal ring inside of it, so it can hold the weight of the Power Amp 18. However, this can fall down if this is attached to something that moves and bounces.
