General

This unit is designed for easy operation under the stress associated with high-speed

pursuit. Most siren functions are accessible with one simple motion without repetitive

activation of switches or automatic timed switching that can interfere with desired

operation.

Power/PA Knob

The Power/PA knob is located in the upper right hand corner of

the front face. It has two functions:

ON/OFF - This knob turns the siren on and off. While in

the OFF position none of the siren functions

will work. The position of this knob does NOT

affect the siren backlighting.

PA Volume Control - This knob also provides you the ability to adjust the public

address volume. It should be set when the vehicle is parked.

Typically you should set the PA volume to the maximum

possible level with no feedback (squeal).

The rotary selector switch controls the primary operating function of the siren.

THUNDER - Ultra-fast changing tone used for maximum attention.

YELP - A rapidly changing tone used in congested areas.

WAIL - A slower changing tone used on highways.

HF - Hands Free - A silent standby mode also known as Horn Ring Cycler.

Allows the user to cycle through the tones programmed for the WAIL,

YELP, THUNDER, and OFF by repeatedly pressing the horn or other switch

connected to the AUX input. Changing the rotary knob to any other

mode will resume normal siren operation.

MANUAL - A silent standby mode that allows push-button Manual, push-button Horn,

and Public Address operation. The siren output winds down when the

MANUAL button is released.

PA - A silent standby mode that allows push-button Manual, push-button Horn

and Public Address operation. The siren output terminates immediately

when the MANUAL button is released.

RADIO - Also known as Radio Repeat, this function amplifies a radio speaker input

for re-broadcast outside the vehicle. The PA remains functional, but no

siren tones are available in this position.
