i get it READ THE MANUAL is the first thing you know how to say.. but maybe try to help with the issue.
the marq lpr is right behind the hpr. there should be a hole cut in your frame to access it.. i would suggest not touching it unless you have an pressure tester.
if your marker is going into full auto when you get on it. try to adjust the trigger and turn up your debounce setting. this i will tell you to go to the manual for. you may also install a magnet kit for the return so prevent this.
