Accuracy Test
This will determine if the radar interface is functioning properly.
1. Press “2
nd
F” followed by seven presses of the Menu. This will put the radar in speedometer test mode. In case
of Motorcycle remote, press “2
nd
F” followed by 7 presses of the “2
nd
Menu” to access the speedometer test
mode.
2. Hit the “+” button to activate the speedometer interface testing. The middle/fastest window shows the reading
of the vehicle speed as interpreted by the radar unit.
3. Drive the vehicle with the cruise control set or maintain a constant speed between 65 and 97 kph.
4. Compare the Patrol reading with the reading in the Fastest/Middle window (radar interface speed). If these
agree within reasonable limits (+/- 5 mph or +/- 8 kph) of each other the radar and speedometer interface are
ready to operate. (These numbers do not have to agree exactly, since the radar derives its patrol speed from
the radar beam, and the radar interface speed is used for comparison purposes only.) Return to the installation
procedure and secure all of the cables and the speedometer interface.
5. If the Patrol reading and the Fastest/middle window readings do not agree, proceed to the
Speedometer
Interface Calibration Procedure
.
6. To exit the test mode, press Stand-by or any transmit button on the radar.
Calibrating Speedometer Interface
In the event that you are installing the Speedometer Interface in a model and type of the car is not listed in the
Ranger EZ pre-defined speedometer interfaces, this special calibration procedure is required. The pre-defined
speedometer interfaces that the Ranger EZ uses are mentioned under “Six presses of the menu button – Selects the
type of speedometer interface” in the
Remote Control
section of this manual. The model and types of the
vehicles mentioned under that section do not need any special calibration procedure.
The following steps are to be followed in order to calibrate a generic speedometer interface.
1. Turn on the radar and set the radar on Stand-by.
2. Press “2
nd
F” and then press the Menu button six times until the display shows “No cAr”.
3. Press the “+” button until “cAr 99” is selected. Wait for the display to blank-out.
4. Press Front Antenna button to come out of Stand-by and go into Moving mode.
5. Ensure that the Automatic Stationary option “Aut Sta” is turned OFF.
6. Drive the vehicle at a steady speed. Variations in speed can affect the accuracy of calibration. The speed of
the vehicle has to be above 10 mph.
7. Press the following keys in sequence without allowing the sequence to time-out. The sequence is as follows,
2
nd
F
Menu 2
nd
F Mov/Sta Lock.
8. The above sequence will put the radar in Speedometer Calibration mode. The display will show “CAL ON”
on the Target and Fast window respectively. The “Lock” sign will light-up. The Patrol window will show the
patrol speed of the vehicle.
9. Press the Lock button again after 5 seconds or so. The vehicle should be going at a constant speed during this
time. “CAL ON” and “Lock” sign is blanked out and display returns to the normal mode. The speedometer
interface is now calibrated.
