Once installed, what is the schedule to have the system calibrated? And how are payments scheduled?

I go in monthly for calibration and make my service payment. You do have the option to do 2 months at a time. I pay $79.50 / month with insurance on the device. Violations cost $53 each time,and you have 4 days to get there for recalibration before you are locked out and cannot start your vehicle

Be careful because any alcohol base substance can cause a violation as well as energy drinks

Monthly unless you get a violation then you got like 2-3 days to get to smart start to have it cleared and pay your fine but you go in monthly to calibrate and pay each time like $73
