Magnitude Control – provides control over the sensitivity of the module to detect moving objects. Low
numbers are most sensitive, high numbers are least sensitive. Magnitude is related to Squelch as the
square root of the number. For example, a magnitude setting of 10 is equal to a Squelch setting of 100
(QI).
