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(s) 
or improper installation.  The following chart shows typical symptoms and possible causes. 
A blown internal fuse doesn't necessarily mean that the unit is bad.  If a speaker or speaker lead 
is shorted the internal fuse will blow before the unit is damaged.  Disconnect the SPKR leads and 
replace the fuse.  If the siren emits a sound when in the Yelp position it is OK.  Check the speaker
(s) or leads for possible shorting.
