*Connecting a Buzzer to the Digital Output to emit sounds as soon as jamming is detected is the most straightforward use of this scenario.

*A relay can be used to disable the starter motor. Usually used with the Immobilizer scenario.

Alternatively, the Digital output can also be connected to an LED visible to the driver to inform the driver when Jamming occurs.''Eventual Records'' parameter can be configured: when it is disabled scenario status value will appear in each AVL record, otherwise it will be appended only to eventual records.

Note that this scenario will not work with Deep Sleep, Ultra Deep Sleep and Online Deep Sleep modes, since they disable the device's GSM module to save power.
