In order for a <br /> unit's location, `MEDIC 1' or`MEDIC 5' for example,to be displayed on the <br /> CADMap,the subunit must be attached to the unit after the unit is logged onto <br /> the system by a NorthStar CAD system dispatcher. <br /> If a unit is transferred to another subunit,the current subunit must be detached <br /> and the new one attached.Failure to follow the abovedefined process in a timely <br /> manner can result in units being incorrectly tracked by AVL and displayed in the <br /> wrong location on the map. When a unit goes to an off-duty status,any attached <br /> subunit is automatically detached. <br /> If a position update is received from a subunit representing an INMOTION <br /> device and the subunit is not attached to a CAD unit,a warning message will be <br /> sent to all CADMsg applications. <br /> 3-3 <br />
