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 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 this fuse will blow before the unit is damaged. Disconnect the speaker leads and replace the fuse. If the siren emits a sound when in the Yelp position it is OK. Check the speaker or leads for possible shorting.

Check or replace the internal fuse by removing the two screws holding the cover to the bottom of the case. The fuse is a standard automotive type rated 15AMP.
