OPERATION
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 oper-
ating mode of the siren.
Radio
- Also known as Radio Repeat, this function amplifies a
radio speaker input for re-broadcast outside the vehicle. No
siren tones or PA operation are available in this position.
The radio must be connected and RADIO VOLUME ADJUSTed
for this mode to function.
Standby
- A silent mode that maybe 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-Tone
which is two alternating frequencies like a
European HI-LO. See OPTION SWITCHES section.
MICROPHONE (PA Override)
The attached noise-canceling microphone is used for public address operation and overrides any
siren tone when the push-to-talk button on the side of the microphone is pressed.
PA VOL
This control adjusts the PA volume. With the vehicle parked, set the PA volume
to the maximum level with no feedback (squeal).
