MAN
-
(Manual)
A silent mode that allows push-button Manual, push-
button Horn, and Public Address operation. The siren output
winds down
when the MAN button is released, or can optionally
sweep tones (see the
Detailed Programming
section on page
17).
ALERT
- A silent mode that allows push-button Manual, push-button Horn
and Public Address operation. The difference between this
mode and the Manual mode is that in this mode the siren output
terminates immediately
when the MAN 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.

Whenever you turn the unit on by rotating the PA button clockwise, the rotary
selector switch will control the primary operating function of the siren.
