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.

Power Supply
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.

No Power
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.

TESTING
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.
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.
Periodic Calibration
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
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).
Power-On Self-Test
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).
