wiring the Shifter to a switched circuit so
that it will turn on/off with your vehicle’s
ignition).

Flashing LED (red) provides visual alert for
incoming laser signals received from the
front of the vehicle.

A built-in photocell will adjust the display
brightness automatically based on the

Laser Transceivers
Your Shifter ZR3 is equipped with a total of
three (2 front, 1 rear) laser transceivers.
These highly sensitive laser transceivers will
detect a laser signal, and respond (or
transmit) a pulsed signal back in order to
“Shift” or confuse the targeting laser gun.
These highly sensitive transceivers
must have a clear view of the road, and
must be installed parallel to the road and
aimed correctly in order to work properly.
See Installation Manual for complete details.
Power and Volume Control
To turn the Shifter on and adjust the alert
tone volume level, rotate the thumbwheel
on Shifter's Display/Controller. Turn the
volume control knob to the left to increase
the audio volume. When you turn the
Shifter on, it will go through a sequence of
alerts and verify communication to the laser
transceivers.
Power-On Indication
After the Shifter’s start-up sequence is
complete, the pilot LED (green) will stop
flashing, informing you that the system is
turned on and functioning properly.
Mute/Remote Mute Button
The Mute Button, located on Shifter’s front
panel, or the installed Remote Mute Button,
allows you to silence the audio alert during
a laser encounter.
To mute the
audio, briefly
press the Mute
Button or the
installed Remote
Mute Button once.
After that laser encounter has passed,
the mute will automatically reset and
the audio will alert you to the next
encounter.
Manual “Receive Only” Mode
The Remote Mute button can also be used
to manually shut off the laser transceivers
once you have corrected your speed. Since
some laser guns provide “jamming” codes
for the officer, this can be useful to avoid
any undue attention.
Simply press the installed Remote Mute
Button, or the mute button located on the
Display Controller twice during a laser alert.
All Shifters will cease to transmit, and the
alert LED will stop flashing and remain on.
This indicates that you are now in “receive
only” mode.
The Shifters remain in the “receive
only” mode for approximately sixty
seconds, giving you time to pass the speed
trap. Once this time has expired, the alert
LED will turn off, and a double beep tone
will be given, indicating that the Shifters are
now back in the “active” mode.
