radio speaker input for re-broadcast outside the vehicle.				No
siren tones or PA operation are available in this position.					MECH
The radio must be connected and RADIO VOLUME ADJUSTed
for this mode to function.					WAIL
Standby - A silent mode that maybe overridden anytime with
the Siren push-button.					YELP
Mech - A simulated mechanical siren tone used anytime.
Wail - A slower changing tone used on highways.					PHASER
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
