VDO SPEED ALERT
Installation Instructions
TO MOUNT THE SPEED ALERT UNIT
a. Make sure the Speed Alert is mounted in a location away from direct sunlight.
b. Install the unit to provide good access from driver’s seat. It should be mounted within easy
reach, eg. The centre console or either side of the dashboard where visible, is an ideal
mounting position.
c. The unit can be mounted on any smooth surface by means of double-sided tape (provided
in the Kit). Remove any wax or polish from the dash or centre console with a recognised
cleaning fluid. Fix the adhesive tab to the smooth panel of the Speed Alert that will make
contact with the mounting surface of the vehicle. Hold the Speed Alert at the casing edge
and solidly apply to the desired position.
Do not press on the display or the front buttons.

ELECTRONIC SPEEDOMETER
In vehicles with electronic speedometers, the Speed Alert signal wire (Blue) can be directly
connected to the speed sensor signal output.
You may need to refer to your vehicles service/repair manual or contact your local Dealer to find
out the speed signal colour wire.
MECHANICAL SPEEDOMETER
In the case of a mechanical speedometer, fit an electronic speed sensor to the vehicle as per the
instructions of that particular unit.
If the speed sensor supplied in the mechanical Speed Alert kit doesn’t suit your application,
contact VDO Kienzle or your supplier for further information on alternative speed sensors.

Operating Instructions
CALIBRATION
The Calibration must be done during the initial set-up or
when battery voltage is lost.
When the battery Positive wire (the last connection
made) is applied to the Speed Alert, the liquid crystal
display (LCD) will alternate between “CL” and “60”.
The display flashes “60” to remind you to calibrate the
unit at 60 Km/h.
To calibrate the Speed Alert to your vehicle, simply follow these steps:
a. Drive the vehicle at a steady speed until the vehicle speedometer indicates 60 Km/h.
b. While retaining 60 Km/h press the “set” button. The unit is now calibrated to your vehicle
and will confirm calibration by giving a single beep and displaying “0”. Your Speed Alert is
only as accurate as your speedometer.
Note
If constant power is lost, due to a flat battery or the removal of a battery terminal, the Speed
Alert will have to be re-calibrated. Simply follow steps “a.” and “b.” above.
If calibration is incorrect reset the Speed Alert into the calibration mode by pushing all three front
buttons at once for a period of 4 seconds.
SETTING THE UNIT
While driving the vehicle at the desired trigger speed (at
or close to the speed limit) press the “Set” button.
This speed is then programmed into the over-speed
warning function, and will be displayed.
When the vehicle is driven at speeds above the trigger speed, the Speed Alert will activate the
audio and visual alarms. The combination, visual and audible alarms are programmable to give
either:
Page 5
a. 6 sets of 2 beeps every 30 seconds or
b. Continuous beeps.
Once the unit is installed the alarm will be set to option
“a.” The continuous beeps option “b can be selected by
pressing the “Set” button for more than 30 seconds. If the
“Set” button is held for another 30 seconds, the alarm will
revert back to option (a.).
TO ADJUST THE TRIGGER SPEED
Fine adjustments of the trigger speed are made by
pressing the ▲or ▼buttons which will increase or
decrease the speed setting in 1 Km/h steps
TO PROGRAM A NEW SPEED SETTING
To set a new trigger speed into the unit (eg. driving into a
different speed zone simply drive to the desired speed
and press the set button the new speed will be displayed
and programmed into the Speed Alert.

TO CANCEL SPEED SETTING
Alternatively, you can hold the ▲and ▼buttons
simultaneously. The display will revert to “0” and the
speed alarm will not operate until a new trigger speed is
set.
HEADLIGHT WARNING
If the lights are left on when the ignition has been turned off, the Speed Alert alarm will beep
continuously and the LED will flash until the headlights are turned off.
TROUBLESHOOTING
PROBLEM After calibration of the unit, the display shows 20km/h whenever SET button is
pressed.
SOLUTION Speed signal missing. Check for correct connection of blue signal wire.
PROBLEM After ignition is switched off, Speed Alert beeps, and “OO” flashes on display.
SOLUTION Check that headlights have been switched off, check for correct connection of
white wire. If white wire is not connected, connect it to ground.
PROBLEM Speed Alert triggers at incorrect speed.
SOLUTION Speed Alert requires calibration. To do this, depress all three buttons at the
same time for four seconds. The display will now alternate between “CL” and
“60”. Drive the vehicle at a steady 60km/h and push the “SET” button. The
speed Alert will now be re-calibrated to your vehicle.
