programming 2 stage code alarm shock sens

So im trying to figure out how to program the dual stage shock sensor via the remote on a Autopage rf-425. No directions in any of the manuals on how to adjust the sensitivity. Checked the sensor and no adjustment screw is present. So can anyone please inform me as to the correct procedure for setting it? Thanks in advance for helping to resolve this issue. Neighbors are getting frustrated, and so am I ........

I'm assuming you have the shock sensor that came with the rf425. The shock sensor is wedge shaped. There is an adjustment screw in the thickest part of the shock sensor housing on the top side, the side away from the mounting tabs. It is recessed, and may be difficult to spot. Turning the adjustment screw counterclockwise will reduce the sensitivity. Start with 1/4 turn and retest. Hope this helps.Lectric Guy
