Operation
Manual and Air Horn
MAN and HORN Buttons
The front panel of the LCS790 contains two pushbuttons
that operate the Manual function and the Air Horn.
MAN –
When the selector switch is in the WAIL, YELP or PHSR positions,
pressing the MAN button cycles through to a quicker changing tone (see
table below). These quicker tones are generally used at intersections and
very highly congested areas. Pressing the button once changes to the
next faster tone. Pressing it again changes the tone back to original tone.
With the selector switch in the MAN, ALERT, or HF position, this switch
provides a manually activated Wail siren tone while the button is being
held. This can be used in low noise areas or if you wish to momentarily
alert motorists.
Optional operation includes replacement of the Phaser tone with Two-Tone
(HI/LO) or disabling the Phaser tone entirely (see page 27 of the
Detailed
Programming
section). These options may be governed by State and/or
Local laws.
(NOTE: PHASER and TWO-TONE may be optionally swapped or disabled
(see page 27 of the
Detailed Programming
section).
HORN
– Pressing this button provides a simulated air horn tone. This can be
used to either replace, or to supplement the normal vehicle horn and is useful
at intersections or in high noise areas. This tone will override all other siren
tones.
