E04 = JAM.
Stalker LZ-1 Version 1
An E04 code is very common to see on the version 1 Stalkers, even when targeting vehicles without jammers. This gun has the most "jam code false alerts" of any gun used in the US. This is possibly caused by light sources such as running lights or sunlight reflections. If an officer using one of these guns sees an E04, this isn't probably isn't suspicious by itself, since he probably sees it all the time.
Stalker LZ-1 Version 2
Stalker revised their guns, and on version 2 guns an E04 is very rare to see. No jammer that we have used this gun against triggers an E04. Most likely, this can only be triggered by "brute force" jammers such as the older Lidatek LE-10.
