Operation CONT’D)
PA VOLUME
The PA volume control is provided for public address
volume. This is in the bottom left corner of the control
head. Insert a small, flat blade screwdriver into the PA
volume adjustment port. Turn counter-clockwise
direction to increase the sound level.
MICROPHONE
The integrated noise-canceling microphone
is used for public address operation and
overrides any siren tone when its push-to-talk
(button on the side) is pressed.
ARROW STICK PUSH BUTTON SWITCHES (LCS850 & LCS850-F only)
The LRCO push button
toggles the arrow stick
output through a different
pattern with each push.
(Left arrow, Right arrow,
Center-Out arrow, and Off).
The WARN button will override the LRCO button, and immediately produces a
warning pattern on the arrow stick. When used in conjunction with an arrow stick
that has independently switched heads, the eight LED’s in between the two buttons
provide real time user feedback as to the output of the arrow stick. When used with
logic controlled arrow sticks, the display “simulates” the pattern.
RADIO REPEAT VOLUME
The radio repeat volume is
located within the rear access
cover of the amplifier. This should
be set during installation when the
vehicle is parked. Under normal
circumstances, you should not
need to adjust it again.
First set the volume level of the vehicle’s two-way radio to its normal operating
volume. Turn on the On/Off switch of the hand held controller and press the RADIO
button. The radio should be rebroadcasting through the siren speaker(s). Using a
small flat blade screwdriver, adjust the potentiometer as desired.
PARK KILL
(White Wire)
During installation, the Park Kill input may be connected to a door switch. It will
automatically deactivate any siren tone when the door is opened. The siren tone
will remain off, even when the door is closed, until you change audio modes.
