Controls and Features
Optional Detector Configuration
Display Brightness
SHIFTER’s display brightness is automatically
adjusted to suit ambient lighting conditions
in your car. (The light sensor is located to
the left of the Mute button on the Display
Controller and may dim the display
momentarily when accessing this button.)
Alert Indications – Audible
Since Laser signals are a possible threat no
matter how weak, the SHIFTER ZR4 alerts
you with a full continuous laser alert.
Alert Indications – Visual
Separate front and rear alert lamps (red
LED’s) provide visual indication for
incoming signals.
Once a laser signal is received, the
appropriate alert lamp (red LED) will
begin to flash, indicating that a laser signal
has been received, and that the SHIFTERS
are transmitting back.
If the manual shut off feature is
engaged, the alert lamp (red LED) will
switch to a solid “on” state, and will
remain on until the sixty second timer has
elapsed (see page 3 for more details).
Diagnostics
Your SHIFTER ZR4 comes complete with
built-in self-diagnostic circuitry, and error
indications.
During the start-up sequence, the
SHIFTER display will make certain that all
components are connected and
communicating properly.
On initial start-up, the power-on
indicator (blue LED) will blink. During this
time communications between the front
SHIFTERS, Interface, and rear SHIFTER
are tested. Finally, the Interface and
Display communications are tested. If
everything is working correctly, a double
beep tone is given, and the power-on
indicator will stop flashing and remain “on.”
Error Indications
The ZR4 will test each element of the
system during the start-up sequence. If
communications stop (i.e. cable is
disconnected) an error message is given.
Front SHIFTER Error
If one, or both of the front-mounted
SHIFTERS is not communicating properly,
the front LED on the display controller
will remain on, and a double brap tone
will be heard. This sequence will continue
until the unit is turned off, indicating that
service is required.
Rear SHIFTER Error
The ZR4 can be installed without the
rear laser SHIFTER.
If the rear SHIFTER stops communi-
cating, or is not installed, the rear LED on
the display controller will remain on
approximately 5-10 seconds during start-
up, and a double brap tone is given. Once
this sequence is complete, the rear LED on
the display controller will turn off.
The new Laser SHIFTER ZR4 laser defense
system can be integrated, or “linked” to a
PASSPORT or BELTRONICS radar and laser
detector, creating the ultimate protection
against radar and laser guns. Contact your
local installer for details.
Once the ZR4 Laser SHIFTER is linked
to one of these detectors, all visual and
audible alerts are generated through the
detector, eliminating the use of the
supplied display controller.
Start-Up Sequence
Once the ZR4 has been successfully
installed, the detector will provide
confirmation of this by displaying a “ZR4
Shft” (factory default), “Zr4 Off,” or “Zr4
Rec” message during its start-up sequence.
If both the detector and the SHIFTER
Display Controller are connected at the
same time, both will go through a self-test.
Once the self-test is complete, the Display
Controller will go to “sleep,” relying on the
detector’s display any visual information.
If the SHIFTER Display Controller is
connected, and the detector is turned off,
the SHIFTER Display Controller will
provide all visual indications from the
SHIFTER ZR4.
How to change the ZR4’s setting using
the detector
Once the detector is connected to the
ZR4’s Interface module, you may change
how the Laser SHIFTERS operate. Three
options are available: “Shft” (SHIFTERS
On/factory default), “Rec” (received only),
and “Off” (Laser SHIFTERS will not
receive or transmit).
To change the factory default setting:
1
Enter the Program Mode or
Preferences on the detector. (see
detector owner’s manual for details)
2
Press the REVIEW button until you
reach the “Bands” category.
3
Select the Laser category.
4
Press the CHANGE button to toggle
between “Zr4 SHFT,” “Zr4 REC,” and
“Zr4 OFF.”
5
To leave the Program Mode or
Preferences, simply wait 8 seconds
without pressing any buttons.
Visual Laser Alerts
When a laser signal is received from the
front, the detector will display “F Laser
Shifter.”
When a laser signal is received from
the rear (with the rear SHIFTER installed)
the detector will display “R Laser Shifter.”
