Question

I just bought an LG hbm-750 bluetooth headset for my iphone. The problem is when I try to turn it off it redials the last number and the blue light keeps blinking. Directions say to power off hold 2 seconds and to redial hold 1 second. It automatically starts to redial while I'm still holding down the button. What am I doing wrong and how do I turn it off?
