After you release the TRIGGER the instrument will display the
most recent speed reading and the distance at which it was
captured or an error code. When the most recent speed
reading is displayed, the display screen will look similar to
Figure 17.
•
The speed displays as a
negative number
if the target was
going away from you when it was measured.
• The speed displays as a
positive number
if the target was
approaching you when it was measured.
Jam Indicator
The JAM display indicator (page 15) on the back panel screen may blink
during a measurement, and may be accompanied by the jam tone
(page 21). This indicates that the instrument is being flooded by light
and is having difficulty detecting its own signal. There are two possible
situations:
•
You are targeting a strong light source such as headlights.
-or-
• A targeted vehicle is employing a laser jamming device.
Regardless of the level of interference, you will never get an erroneous
speed reading.
•
At a low level of interference,
a speed may be captured or
an E03 error code may be displayed.
•
At a high level of interference,
an E07 error code will be
displayed.
