Automatic VSS Calibration 
Once the VSS cables are properly installed, the radar is ready to synchronize the vehicle’s VSS signal with the radar’s 
ground speed readings.  The calibration sequence will determine the proper ratio between the VSS signal speed and the 
radar ground speed.  The numeric result is stored in the radar’s memory (called a calibration factor).    
Every time the radar is turned on and then operated, the auto-calibration routine is triggered.  The very first time the radar 
is installed and operated, the auto-calibration sequence may take a few minutes (since there is not a previously stored 
calibration factor to verify).  During successive operations, in the same vehicle, the auto-calibration routine will seem 
instant. 
First Time Calibration (or Installing the Radar in a New Vehicle) 
To auto-calibrate you will need to operate (with the radar transmitting) in the moving mode for a few city blocks.  The 
radar can complete the calibration sequence much faster if the speed of the vehicle is varied above 20 mph (don’t merely 
drive at a steady speed at first).  When you see the patrol speed window consistently showing an accurate speed, then the 
auto-calibration sequence has been successful. 
Automatic Moving / Stationary Selection 
When the radar is receiving VSS signals, and it has been calibrated, the unit should automatically switch between moving 
and stationary operation modes when the patrol vehicle moves and stops.   While moving, the MOV/STA key will not 
override the moving / stationary mode selected by the VSS steered radar. 
Low Speed Speedometer Problems 
In some vehicles, the VSS signal is non-existent at speeds below 5-10 mph so you may see no change in the car’s 
speedometer reading until the car exceeds 10 mph.   In these cases, the Stalker PATROL radar will also not be switched 
into moving mode until the patrol car exceeds 10 mph.
