Important: The factory sets the theft deterrent shock sensor to a middle range of sensitivity. Depending on your area or usage, the factory setting may be too sensitive or not sensitive enough. Make sure that the tamper label on the knob that adjusts the shock sensor is not broken or altered. If the label is broken or altered, the shock sensor may be misadjusted to a setting that is less or more sensitive. | |||
