probably need to change the battery on the board, if you do change the parameters back to what you want, when you turn off the power, they will default again. i would get a battery and change it before you make the changes. pm me your email, and i will send you a manual. if you get the tool from ECI, it does come with a little manual that gives the basics. i just changed a couple batteries for this exact reason on a new job we just got. good luck
