The siren may be left on any time the vehicle is in operation. The power should be turned off when vehicle is not being used to conserve battery power. The Rotary Function Switch selects various operating modes. These modes are as follows: RADIO This mode reproduces, or repeats, the output of a radio. The radio must be connected and RADIO VOLUME ADJUSTed for this mode to function. No overrides available in this mode. HORN Also considered a standby mode. Horn and PA Override available in this mode. MAN The siren tone is controlled Manually with SIREN button. PA Override available in this mode. WAIL The siren produces a normal rise-fall tone pattern. This mode should be used on highways or areas with constant traffic flow. Yelp and PA Override available in this mode. YELP The siren produces a moderate warble tone. This mode should be used in lightly congested areas. Horn and PA Override available in this mode. PHASER The siren produces a very fast warble tone. This mode should be used at intersections or in highly congested areas. Horn and PA Override available in this mode. 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. The siren tone resumes when the button is released. (This feature is not available in WAIL mode.) YELP OVERRIDE -Available only in WAIL mode. By momentarily pressing the SIREN button the tone output is switched to the Yelp tone. Pressing the button again switches the tone output back to Wail. RADIO VOLUME ADJUST The RADIO VOLUME ADJUST is a one time setting which depends on the radio connected and its normal volume. The siren cover must be removed to access the adjustment. The cover is held in place by a snap-fastener on the back of the unit. While holding the case on the sides press hard with your thumbs on the back of the unit. The chassis will slide out the front. Switch siren to RADIO mode and turn on the power. With the volume on the radio itself set to normal level, set the RADIO VOLUME ADJUST to the RADIO VOLUME ADJUST desired level. Turn off power and press the chassis back into the cover. TB0324B Page 5 of 7 10/18/03 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. 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.
