-To find this problem put your system in +To find this problem put your system in [[https://​www.youtube.com/​watch?​v=MqfSMlpJvAc|continuous power mode]]. If the shooting LED of the gun is not on then you have a problem.

 +  - Use an oscilloscope to make sure that the input to the transmitter board has an amplitude of 3.3V. 
 +  - Check the gun to make sure that the gun LED is working. ​ A [[tester|gun tester]] was built to help with this diagnosis. 
 +  - Check the supply voltage of your transmitter board.

 +===== You have to set the 'Fudge Factor'​ too high ===== 
 +With system set in [[https://​www.youtube.com/​watch?​v=PYiv2PgLo6k|shooter mode]] you should be able to point the gun at various different light sources (fluorescent lights, sun, monitor, etc.) and not record a hit.  If a hit is recorded without it being shot (called a false positive) then the 'Fudge Factor'​ needs to be increased. ​  
 + 
 +Increasing the 'Fudge Factor'​ reduces your maximum range. ​ To decrease the 'Fudge Factor'​ you need to investigate the noise signals. ​ The oscilloscope is the best way to sample your noise signal. ​ The oscilloscope probe should be paced after the receiver board and the [[fft|oscilloscope FFT]] should be used.
