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 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 SPK leads and replace the
fuse. If the OUTPUT light on face of unit comes on with Wail switch activated the amplifier is OK.
Check the speaker or leads for possible shorting.
