Hold down the power button until only the lcd is lit. When this happens ur in the safe mode where you can adjust game time and reset the shot counter but, the marker is not armed. If ur eyes are on there should b an eye shape lit up on the lcd. To turn them off, hold the foreward most button, i think its "B"? neways if that dosent work try arming the marker and then holding the same button, they should turn on and off after holding down that button for only a few seconds.
