Also clarifies how to handle silent running for me and my crew
Note that searching for random silent running icons in the vicinity is one way to get aware of their presence (determine that they are present).
The intent here is that there might also be other ways to also become aware (or determine that they are present). If you (or any of your team members) for example physically see a specific device then you would also be considered aware of it (you already determined that it is present) and can take a matrix perception test to spot the device icon of this specific device (in this case there is no need to randomly check all other 2000 silent running devices in the vicinity. since you are aware of this device you just attempt to spot the device icon of this specific device directly).
Example;
You see a vehicle parked further down the street (among other parked vehicles).
Matrix perception to spot the device icon of this specific vehicle.
If it is running silent then it get to oppose the test
If it is not running silent and within 100 meters then spotting of its icon is automatic.
Example 2;
The team run into a door locked with a maglock (in a facility that have many other locked doors).
Matrix perception to spot the device icon of this specific maglock.
If it is running silent then it get to oppose the test
If it is not running silent and within 100 meters then spotting of its icon is automatic.
