SERVICE 
This unit is designed to provide years of reliable service under even the worst conditions.  Many 
times there may appear to be a problem with the unit when the true problem is in the speaker, 
controlled devices, or improper installation.  The following chart shows typical symptoms and 
possible causes. 
 
A blown siren fuse doesn't necessarily mean that the unit is bad.  If a speaker or speaker lead is 
shorted the fuse will blow before the unit is damaged.  Disconnect the SPKR leads and replace 
the fuse.  If the OUTPUT light comes on with siren power enabled and Wail mode selected it is 
OK.  Check the speaker or leads for possible shorting.
