This Chapter provides a listing of Alarm Codes to be used during diagnostics and repair activities.  
Please refer to Chapter 6 for troubleshooting information. 
 
1.  If the F22 detects an error, an alarm tone may sound.  The alarm tones are given in Morse code, 

where “.” (dot) indicates a short alarm for a duration of 0.26 second and “—”  (dash) a long 
alarm for a duration of 0.78 second. The interval between each alarm tone is 0.26 second. 

2.  If the unit’s self-diagnostics detect an error and sound the alarm tones, then the unit will be 

disabled and will not function until the malfunction is corrected. 

 

 Maintenance technicians can use these error codes for troubleshooting, 

however the best solution is usually replacement of the defective module.
