Hi you can activate the on Demand tracking/Panic Button by following these steps
1. Go to the Data Acquisition settings
2. Under on demand tracking fill the Period( Period for data saving/sending) and the Duration ( Duration of the on demand tracking )
The Activation by setting is where your panic button connected.
