You simply point it at whatever item you want to reduce the static charge on (typically an LP, but it can be used on CDs as well), and squeeze the trigger smoothly both in and out. I forgot what is actually happening when you pull the trigger and release it, but I think that when you pull the trigger, it puts out positive ions and when you release it, it produces negative ions. The idea is to bring the charge to a neutral state, so you don't have a strong static charge. It's a great thing to have during the winter. A discwasher does the same thing when it's used with fluid: otherwise it generates a static charge.
