RADIO REPEAT VOLUME
To Adjust the Radio Repeat Levels:
Before using the 295HFANC, the
Radio Repeat output volume must
be adjusted to satisfactory operating
levels. To adjust this level, a small,
flat blade screwdriver needed.
Locate the Radio Repeat adjustment
port (potentiometer) to the right of the
Rotary Knob on the face of the control
head. Set the volume level of the vehicle’s two-way radio to it’s
normal operating volume. Turn the Rotory Knob on the control
head to RAD to activate Radio Repeat. Insert the screwdriver in
the Radio Repeat adjustment port and turn in clockwise direc-
tion to increase the sound level.
MAN BUTTON
The Manual button generates a variety
of tones, depending on what position the
rotary knob is in. For further explanation
of this button’s function, refer to Rotary
Switch Operations.
SI-TEST
®
& DIAGNOSTIC
INDICATORS
SI-TEST
®
is a diagnostic feature of the
295HFANC & allows the operator to
confirm the proper operation of the siren
speakers connected to the unit without
activating an audible siren tone. To
initiate SI-TEST
®
cycle, set the rotary
knob to the RAD position. Now press and
release the MAN button. As the siren is
tested, its diagnostic indicator will turn on steady for about 1.5
seconds if no problems are detected. If the indicator flashes, or
does not light at all, a problem with either the siren, speakers, or
wiring has been detected. Check the wire connections of the
failed speaker and repeat the SI-TEST
®
. If the speaker fails to
test again, have the siren itself inspected by a qualified techni-
cian.
NOTE:
Installed speakers are tested by generating an
ultra-high frequency tone through each speaker. Although these
tones are inaudible to humans, be sure that there is nobody
within 5 feet of the speakers when SI-TEST
®
is running.
HORN BUTTON
Holding the HORN button on, generates
an AIRHORN tone whenever the siren is
powered up.
Operating the 295HFANC Controls:
POWER SWITCH
This switch has two positions. Down / Off
Up / On When this switch is Off, the unit
will not function. When the switch is On,
the siren is functional and may be
activated at the operator’s discretion.
NOTE: If the 295HFANC is
connected to the vehicle’s horn ring
circuit, the vehicle horn is disabled when
the power switch is in the ON position.
ROTARY SWITCH
The Rotary Knob controls the siren and
PA (Public Address) functions of the
295HFANC. There are 7 positions
that may be selected. Each position and
it’s function is outlined under “Rotary
Switch Operations”.
VOLUME KNOB
The Volume Knob controls the volume of
Public Address function. Volume is
increased by rotating the knob in a
clockwise direction. Rotating the volume
knob in a counter-clockwise direction
decreases the volume produced by
these features. The volume knob has no
effect on any siren tones produced.
