This pertains to Recoil AimTrak Light Guns only.If you are experiencing issues with the Recoil on your AimTrak Light Gun please try the following steps:Be sure that you are standing in relatively same spot as when you calibrated your Light Guns. A common thing we see is people are standing too close, too far away or too far off to one side or the other and thus the gun will not pick up the IR signal and the recoil will either not work, or be intermittent. Hint: place a piece of tape on the floor where you calibrated your gun(s) so you know exactly how far away to stand when playing!Hold the gun horizontally (sideways) and try activating the recoil about 20 times in succession. Then do the same thing with the gun held upright and tipped slightly upwards.Let us know what the results are of this test so we can determine what the next step will be.If you have a Retro Active Arcade machine with Light Guns and you are experiencing issues with the recoil, be sure you are standing at about 4 to 5 feet away from the screen when using the Light Guns. This is the distance we have calibrated the guns at.NOTE: AimTrak Light Guns come with a manufacturer's warranty. This means if the gun is deemed defective it will not be replaced, but rather repaired.
