Maintenance of Your
Radar Detector
Your ESD-9860 is designed and built to
give you years of trouble-free performance
without the need for service. No routine
maintenance is required.
If your unit does not appear to be
operating properly, please follow
these troubleshooting steps:
Make sure the power cord is
properly connected.
Make sure the socket of your vehicle's
cigarette lighter is clean and free
of corrosion.
Make sure the power cord's cigarette
lighter adapter is firmly seated in your
cigarette lighter.
Check the power cord fuse. (Unscrew
the ribbed end cap of the cigarette
lighter adapter and examine the fuse.
If required, replace it with a 1-amp
fuse only.)

UNDERSTANDING RADAR & LASER
Does weather have any affect
on LIDAR?
Yes. Rain, snow, smoke, fog, or airborne
dust particles will reduce the effective
range of LIDAR and can, if dense enough,
prevent its operation.
Can LIDAR operate through glass?
Yes. Newer LIDAR guns can obtain
readings through most types of glass.
However, the laser pulse also can be
received through glass to trigger an alarm
by your ESD-9860.
Can LIDAR operate while in motion?
No. Because LIDAR operates by line of sight,
the person using it cannot drive the vehicle,
aim, and operate the gun all at the same time
.
Is LIDAR legal to use?
Yes. It is legal in all 50 states.
Some common questions about LIDAR include:
Strobe Alert
™
Special strobes mounted on the light bars of
authorized emergency vehicles (fire trucks,
police cars, ambulances) automatically change
traffic signals as the vehicle approaches an
intersection. These strobes and the special
strobe detectors located on the traffic signals,
introduced fairly recently by 3M and Tomar,
are already in use in more than 1000 cities
nationwide. Cobra’s exclusive Strobe Alert™
detector will detect these special strobes and
give an Emergency Vehicle alert.
When you receive such an alert, please watch
for an approaching emergency vehicle and pull
over to allow it to pass. To inquire about
coverage in your area, contact your local fire
and police departments.
LIDAR (laser)
The correct name for the technology that most
people refer to as laser is actually LIDAR,
which stands for Light Detection and Ranging.
LIDAR operates much like radar. Its signal
spreads out like a radar signal, though not as
quickly. Unlike radar, LIDAR must have a clear
line of sight to its target vehicle throughout
the entire measurement interval. Obstructions
such as sign posts, utility poles, tree branches,
etc., will prevent valid speed measurement.
