To Adjust the Radio Repeat Levels...

Before using the 295HFS5, the Radio Repeat output volume must be adjusted to 
satisfactory operating levels. To adjust this level, a small, flat blade screwdriver is needed.

Radio Repeat Volume

Locate the Radio Repeat adjustment port (potentiometer) to the right of the rotory knob. Set the volume 
level of the vehicle’s two-way radio to it’s normal operating volume. Turn the Rotory Knob to RAD to acti-
vate Radio Repeat. Insert the screwdriver in the Radio Repeat adjustment port and turn in a clockwise 
direction to increase the sound to it’s maximum desired volume.

Microphone Volume Knob (PA)

Locate the Microphone adjustment knob above the microphone cord. With the vehicle in an enclosed area, 
turn the Rotory Knob to PA and speak into the microphone. While speaking, turn the volume knob in a 
clockwise direction to increase the volume. Continue to increase the PA volume until audio feedback 
occurs. Turn the knob in a counter-clockwise direction to eliminate feedback and set the PA level to maxi-
mum volume

Operating the 295HFS5 controls...

Power Switch

This switch has two positions: Down (295HFS5 - Off) and Up
(295HFS5 - On). When this switch is in the Off position, the
WS295HFS will not function. When the switch is in the On
position the siren is functional and may be activated at the
operator’s discretion. 

NOTE:

 If the 295HFS5 is connected to the

vehicle’s horn ring circuit, the vehicle horn is disabled when
the 295HFS5 power switch is in the ON position.

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 the Rotary knob section of this manual.

Rotary Knob

The Rotary Knob controls the siren and PA (Public Address)
functions of the 295HFS5. There are 7 positions that may be
selected. Each position and it’s function is outlined below:
