This can be used to supplement the normal vehicle horn and is useful at intersections or in low noise areas. This tone overrides other siren tones. Horn may be disabled. See OPTION SWITCHES section. MICROPHONE The attached noise-canceling microphone is used for public address operation and overrides any siren tone when the button on the side (PTT) is pressed. VOLUME CONTROLS Controls are provided for radio repeat volume and public address VOLUME volume. These should be set when the vehicle is parked. Set the RAD volume with the selector switch in the Radio position and the radio volume set to desired level. Set the PA volume to H L H L YELP WAIL STBY RADIO the maximum level with no feedback (squeal). RAD PA AUXILIARY INPUT During installation an auxiliary input may be connected to the horn ring or other switching device. It provides the same operation as pressing the Horn button or optionally the Man/Phsr button. CUTOUT During installation, a cutout input may be connected to a door switch. It turns off any siren tone when the door is opened. The siren tone will continue to be cut off even when the door is closed. Changing any switch or input will restore normal function. HORN RING CYCLER 2 (Optional) Available while selector switch is in standby, repeatedly tapping the horn ring or other switch will cycle through Wail, Yelp, and Phaser tones. Tapping the horn ring twice quickly will stop siren tones. Holding the horn ring produces horn. See OPTION SWITCHES section for further details. 05/07/05 CP4874B SA-500-20 Installation and Operating Instructions Page 7 of 8 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.
