A:Answer Thanks for your inquiry. With our JBL PartyBox 310, first, check if anything is blocking the handle, like packaging or debris. Then, try gently wiggling the handle while applying light pressure to see if it loosens. If it’s still stuck, inspect the locking mechanism to see if it’s misaligned or stuck, and try resetting the handle by pushing it down fully and pulling it up again. If you need more help please contact customer support.
