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 desired level. Turn off power and press the chassis back into the cover.
