I just recieved my x-mas present to myself that included two 4sevens lights. Having problem with the Quark x tactical 2x123. Program not seeming to accept. Have mutiple 4sevens tactical lights & am experienced with procedure. Even followed the directions all though I programmed the quark tac 1AA 1st with no problem. After my initial 4 loosening turns from tightened position I do not get the 3 blinks to begin program.
Any help greatly appreciated.
