Jam Codes
Jam Codes are operational indicators on some laser guns that notify the officer if the gun is potentially being jammed. It is important to know if jam codes will affect you, especially in areas where the use of laser jammers is prohibited. Below is the general status of jam codes on the laser guns used in the USA: Kustom Prolaser III, II, I, ProLite 
 These guns do not have any type of JAM indicator. LTI Ultralyte, Marksman 
 E07 = JAM (Along with JAM indicator on the display, and a distinct audible tone to indicate jamming). It is rare to see E07. In all of the GOL jammer tests, no jammer we have tested has ever caused this code to be displayed. The only known jammers that trigger E07 are the older Lidatek LE-10 and Target LE-850. Newer, well-established jammers currently on the market will not trigger an E07. False alerts are rare, but sometimes bright sunlight can trigger an E07. Stalker LZ-1  E04 = JAM The Stalker LZ-1 has frequent "jam code false alerts", perhaps more than any other US laser gun. An E04 code is very common to see on the Stalker, even when targeting vehicles without jammers. This is possibly caused by other light sources such as sun reflections or running lights. If an officer sees E04, this isn't automatically suspicious by itself, since he probably sees it all the time. Laser Atlanta SpeedLaser  JA-1, JA-2, JA-3 in HUD (indicates potential jamming) Jammer1, Jammer2, Jammer3 on LCD (indicates that a jammer is positively detected) Laser Atlanta has taken jammer detection a step further by identifying the "type" of jammer. Jammer detection on the Laser Atlantas is a relatively new feature. Guns produced up until July 2005 did not utilize JAM codes. Guns produced after July 2005 should have jammer type detection, and Laser Atlanta can update the software in older guns to add this feature. Reportedly, this is sometimes prone to "jam code false alerts" just like the Stalker LZ-1. We'll report on this more in the future, as soon as the jammer companies have had some time to address this new threat. |
