TM, the unit changes it’s own schedule through the condition of the vehicle and doesn’t require a
message with a status change be sent to the workstation in order to change it’s location
schedule. Also, since a location schedule can also be stopped due to the vehicle’s condition
(Ignition off and Not moving), a lot of unnecessary locates and locations requests are
eliminated thereby, reducing airtime usage.
