OVERRIDE FUNCTIONS PUBLIC ADDRESS (PA) OVERRIDE -By pressing the microphone button any siren tone output is turned off, allowing the operator to use the siren as a public address amplifier. The siren tone resumes when the button is released. (Hold the microphone close to your lips for proper operation and adjust the PA VOLume Control) HORN OVERRIDE -By pressing the SIREN button the siren tone output is replaced by the horn tone.

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 rear panel 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.
