Strong signals from nearby radio transmitters may interfere with 
operation of S 

. The RFI indicator (Fig 34) signals 

that an interference source has been detected.  Speed readings are 
inhibited when this occurs to prevent the possibility of false 
readings.  The interference source may be the vehicle’s two-way 
radio, another nearby transmitter, or an illegal radar-jamming 
device.

A low voltage condition from the vehicle's electrical system will 
cause a Lo V indication (Fig 35), and will inhibit speed readings.  
An extremely noisy vehicle electrical system may result in false 
readings or erratic operation.  If this condition occurs, a two-
conductor, shielded cable should be connected directly from the 
vehicle battery to the cigarette-plug on the dash.  This should 
eliminate any problems from vehicle electrical noise.

If you get no power to the unit, first check the fuse in your radar by 
unscrewing the silver contact tip at the bottom of the cigar plug and 
removing the fuse. Check the fuse to see if it has blown. If so, 
replace with a new fuse and try to locate the cause. If the fuse is 
okay, check the fuse to the vehicle’s cigar plug. If this fuse is also 
okay, place the radar in a different vehicle or try a different radar in 
your vehicle. 

 

In order to ensure continued compliance with FCC rules, meet legal requirements for admissibility of radar speed 
measurements, and verify full operating performance, the following test procedures are recommended.  If the unit fails any 
of the tests, it should be removed from service until the cause of the problem is corrected. 

We recommend that the following performance characteristics should be verified on a regular basis: 

1.  Transmitter frequency is within specification on licensed operating frequency. 
2.  Unit indicates correct speed (± 1 mph) when reading a target of known speed. 
3.  Unit detects targets of good reflectivity over unobstructed, flat terrain at distances of 1/2 mile, or more, when set for 

highest sensitivity  (SEn 4). 

Each time the unit is powered on, an automatic self-test is performed 
to verify that the unit functions.  The display indicates 888 888 888 
(Fig 36) during the test.  A 4-beep “happy” tone indicates the 
successful completion of this test.  If a problem is detected, FAIL 
will be displayed along with a 15-beep tone. Immediately after 
power-on, and while all display segments are illuminated, pressing 
the SELF TEST key will display the software version followed by 
the transmitter frequency (see page 12).
