When GSM signal jamming is detected the scenario is activated, an event record is generated{{{text_dout| and digital output status is changed to 1 when configured}}} once ''Jamming'' timeout runs out. If jamming ends during timeout countdown no event will be generated{{{text_dout| and output will not be controlled}}}.<br />''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.<br />{{{jamming_dout|info}}}

When device detects GSM signal jamming, it activates the Jamming scenario.  Device then starts a configurable timeout before responding that is inteded to reduce false positives. After the timeout ends, the device generates an event record{{{text_dout| and digital output status is changed to 1 when configured}}} If device regains GSM signal before the countdown ends, no event will be generated{{{text_dout| and output will not be controlled}}}. This Digital Output activation can be used to trigger measures to disrupt potential thieves using GSM signal jamming to steal your vehicle.

* Connecting a Buzzer to the Digital Output to emit sounds as soon as jamming is detected is the most straightforward use of this scenario.
 +
* The Digital Output can be directly connected to the vehicle's alarm system to ensure the thief can not avoid triggering it.
 +
* It can also be connected to the central lock system to ensure that all the doors are locked.
 +
* A relay can be used to disable the starter motor.

<br />''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.<br />{{{jamming_dout|info}}}

<br />Note that this scenario will not work with Deep Sleep, Ultra Deep Sleep and Online Deep Sleep modes, since they disable the device'sGSM module to save power.<br /><br /><br /><br /><br /><br /><br /><br /><br />
