Public Address Operation

The Public Address feature amplifies and broadcasts the user's voice over the siren speaker.

2.2.1

Control Head/DEK-Plus

To activate the Public Address function, momentarily press the PA button. The corresponding light-

emitting diode (LED) will light up and the PA feature will be activated.

The control head display will temporarily show the current PA volume setting. To set the PA volume,

rotate the radio's volume control (the rotary knob on the control head).

NOTE: If you adjust the PA volume with the rotary knob on the control head, it will change the radio's

volume setting based on the position of the knob.

To use the Public Address feature, press the Push-To-Talk (PTT) button and speak into the

microphone. Your voice will be amplified and broadcast over the siren speaker.

NOTE: The PTT button cannot be used to transmit while the PA feature is activated.

If the Public Address and Siren options are both activated, the Siren function will be overridden when

the PTT is pressed. The Public Address feature will have priority, and any siren tone or incoming

radio signals (if in External Radio mode) will be abruptly muted.

To turn off the Public Address, momentarily press the PA button again.

Siren Tone Operation

Wail, Yelp and Hi-Lo siren tones are broadcasted over the siren speaker. Use the Siren function to

toggle between siren tones when broadcasting.

2.3.1

Control Head/DEK-Plus

To turn on the Siren function, press the Siren button momentarily. Then press the Wail, Yelp, or Hi-

Lo buttons to broadcast the desired tone. The corresponding LEDs light up and the control head

display temporarily shows the selected siren tone.

Any time the siren tone is changed, the display will briefly show the newly selected tone (even if the

Siren function is off). To change the tone, press the Siren button on the DEK-Plus or Sirn button on

the control head momentarily.

If the Horn-Ring accessory is connected, you can change the siren tone by pressing the vehicle's

Horn-Ring while broadcasting a siren tone. (The operation of the Horn-Ring feature is shown in

Table

2-1.)

NOTE: You can change the siren tone at any time. The Siren function does not have to be activated.
