OPERATION

Sound Hazard - Sound level from siren speaker (>120dBA @ 10 feet) may cause hearing damage. Do not operate siren without adequate hearing protection for you and anyone in immediate vicinity. (Ref. OSHA 1910.95 for occupational noise exposure guidelines)

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.

SELECTOR SWITCH

The 6-position rotary selector switch controls the primary operating mode of the siren. Radio - Also known as Radio Repeat, this function amplifies

a radio speaker input for re-broadcast outside the vehicle. The radio must be connected and RADIO VOLUME ADJUSTed for this mode to function. Standby - A silent mode that may be overridden anytime with

the Siren push-button. Mech - A simulated mechanical siren tone used anytime.

Wail - A slower changing tone used on highways.

Yelp - A rapidly changing tone used in congested areas. Phaser - A very rapidly changing tone used at intersections

or in highly congested areas. May be optionally replaced with Two-Tonewhich is two alternating frequencies like a European HI-LO. See OPTION SWITCHES section.
