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), 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 internal fuse will blow before the unit is damaged. Disconnect the speaker leads and replace the fuse. If the OUT/DIM light comes on with power on and Yelp selected it is OK. Check the speaker(s) or leads for possible shorting.
