Try locking in a speed

This is a good time to try the lock function.  Place a ringing fork in front of the antenna again.  While the 
readout is displaying a speed in the Target window, press the remote’s “Lock” button.  Note that the lock, 
which is located directly under the Ranger EZ 's middle window is lighted, designating that a speed has been 
locked into the radar. 

Place the radar in Standby mode, by pressing the “Stnby” button.  Notice that the speed of the tuning fork is 
now displayed on the face of the radar in the Target window.  

Press the “Range” button on the remote.  Notice that the target speed has now been displaced by the range 
(distance) of the tuning fork.  The resolution of the radar is 10 yards (or meters), and the distance (0 or 10) 
corresponds to the distance of the tuning fork at the time the speed was locked in.  After a few seconds, the 
distance information will disappear and be replaced by the speed information.  However, the distance 
information is preserved on the range bar at all times. 

Every time that the lock button is pressed, the radar will record the speed(s) displayed in the Target and 
Fastest windows into memory.  When you place the radar into Standby, the locked speeds will be displayed, 
along with the operating mode at the time the speed was locked will be displayed in the Mode window. 

To clear a locked speed, press either the “Front” or “Rear” antenna button.  

Locked speeds are also erased in other ways.  If the radar is placed into Standby, the locked speed is 
preserved, but if the Ranger EZ is then made to transmit again, the locked speed is cleared.  (This is an IACP 
requirement.)  Also, locked speeds are automatically cleared 15 minutes, unless otherwise requested, after 
they are locked to preserve the integrity of the evidence.  The automatic lock clearing is preceded by a 30 
second countdown if the Ranger EZ is in Standby to inform the officer of the imminent clearing of the display 
so the officer can record the speed before it is erased.  

A double click of the “Lock” button will also clear the lock window. 

Perform moving mode tuning fork tests 

Place the Ranger EZ into moving mode by pressing the “Mov/Sta” button on the remote.  If the radar is not in 
opposite direction moving mode, press the “Opp” button.  Turn the transmitter on to the front antenna by 
pressing the raised “Front” button.  Strike the lower frequency fork on a hard nonmetallic surface and hold the 
ringing fork in a fixed position two or three inches in front of the antenna with the narrow edge of the fork 
facing the antenna.  The speed will be shown in the patrol window.  You may have to move the tuning fork 
gently toward and away from the antenna in order to get the radar to read it properly.  This is because a tuning 
fork vibrates both toward and away from the radar, and the radar is expecting to see a target moving either 
toward it or away from it, but not both directions at once.  While continuing to hold the ringing fork in place, 
strike the other fork and hold it next to the patrol speed fork.  Both forks must be vibrating while being held 
an equal distance from the antenna.  The radar should display the difference between the forks as the target 
speed.  For example, for forks marked 35 mph (56 KPH) and 65 mph (104 KPH), the patrol would read 35 
(56 )(low speed fork) and the target would read 30 (48) (high-speed fork minus low speed fork).
