The sensitivity can vary by as muchas 20% under extreme temperature conditions. You may wish to reduce thesensitivity in hot weather and increase sensitivity in cold weather.False AlarmsIf the shock sensor is not working well or at all, it may be that the suspended element inside the case was jolted out of position.
