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(s) or improper installation. The following chart shows typical symptoms and possible
causes.
A blown amplifier fuse doesn't necessarily mean that the unit is bad. If a speaker or speaker
lead is shorted this 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.
