If two blips show simultaneously in a wide zone, they will be counted as one.  Thus in highway 
and counting applications multiple slice zones are useful in rare cases where it is necessary to 
cover a wide lane.  
⇒  Use UP/DOWN keys (or click SIZE arrows) to increase or decrease the size of the zone (to 

multiple range slices). 

⇒  After all zones are positioned, Press ENTER, click OK or type O to close the window. 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 

 
Fine Tune 
“Splashing” is defined as a single vehicle (mainly trucks)  causing two blips in adjacent detection 
zones. A vehicle straddling two lanes or the detection zone straddling two lanes may be the cause.  
It results in over-counting and is undesirable.  

Fine Tuning minimizes splashing, by making small adjustments to the size of all range slices 
(about 2% of the range per step for a maximum of 

±10%). Farther range slices are affected more 

than closer ones. When the Fine Tune setting is changed to correct a splash, some vehicle blips 
may shift out of the defined zones. It may be necessary to re-enter ZONE SETUP to redefine 
zone positions, particularly further zones. Fine Tune is also used to reduce the effects of barriers 
on detection in nearby lanes. Adjust Fine Tune to confine barrier signals to a single range slice. 
Note: The effect of Fine Tune is only shown on the screen by the behavior of vehicle blips.
