Location
Selecting the proper location to mount the Cobra
ESD-9100 is very important for optimum performance. Both radar and laser transmissions pass
through glass but not through other objects.For
this reason the Cobra ESD-9100 lenses must not
be blocked. It should have a view of the rear window to take advantage of Laser Eye 360˚ detection. It is best to locate your detector as low on
the front windshield as possible.
Examples of metal in the windshield area that can
block or weaken incoming radar/laser signals:
1.Windshield wiper blades .
2. Mirrored sun screens.
3. Regular tinted glass does not affect radar
reception,although the darker tint at the
top of the tinted windshield prevents laser
light from penetrating.
4. Heated windshields,currently available as
an option for some Ford® (Instaclear) and
GM® (Electriclear vehicles act as an impenetrable barrier to radar signals). If in doubt,
check with your dealer to see if this applies
to your vehicle.

Exercise Caution.
Facts About the Safety Alert® Traffic
Warning System
FCC-approved Safety Alert Transmitters emit
microwave radar signals to indicate the presence of a
safety-related concern. Depending on the frequency of
these signals, as set on the transmitter,the outgoing
signal can indicate whether the transmitter is on a
speeding emergency vehicle or train,or at a stationary
road hazard location. These microwave signals are
located in the K-band and as a result,any radar detec tor which detects K-band radar will detect these Safety
signals as standard K-band radar alerts.However, unlike
a standard radar detector, your Cobra ESD-9100 is
designed to differentiate between a standard K-band
alert and a Safety Alert warning.
Safety technology is relatively new so the number of
transmitters in operation is still growing. You may not
receive Safety Alert on a daily basis and should not be
surprised to encounter some emergency vehicles, road
hazards or trains not yet equipped with these transmitters,therefore failing to pr ovide a signal.As Safet y
Transmitters become more prevalent (the number of
operating transmitters is growing every day),these
Safety Alerts will become more common. The Safety
Alert Transmitter is in use in all 50 states in limited
quantities.
Facts About Strobe Alert™
Alerts motorists to over 50,000 emergency vehicles
equipped with strobe transmitters that activate red
lights at traffic intersections in emergency high speed
situations.
Note
Strobe Alert™ is available
in over 1,000 cities and
works with Tomar and
Opticom systems. Call your
local Fire/Police department for your area coverage or area in which you
will be traveling.

Radar Frequencies
There are now three frequencies that have been
approved by the FCC (Federal Communications
Commission) for use in speed monitoring
equipment.They are:
X Band (10.525 GHz),K Band (24.150 GHz)
Ka Band (33.400-36.000 GHz)
Your Cobra ESD-9100 can detect signals in all
three radar bands including photo radar and
STALKER radar which use the Ka band, and
Cobra’s Safety Alert signals on the K band.
Facts About LIDAR (Laser)
What is LIDAR?
LIDAR stands for Light Detection And Ranging.
While everyone refers to it as LASER the correct
name is LIDAR.
How does LIDAR work?
LIDAR operates a lot like RADAR.Like RADAR,it
spreads out. Not as quickly, but it does spread,as
shown on the diagram below.
Radar
Frequencies
Facts About
LIDAR (Laser)
LIDARs must have a clear
line of sight to target a
vehicle during the entire
measurement interval.
Intervening objects such as
signposts,utility poles ,tree
branches,etc.,will prevent
a valid speed reading.
Maintenance
Facts About
LIDAR (Laser)
Does weather have any effect on LIDAR?
Yes,rain,snow, smoke,fog, and airborne dust
particles will all reduce the effective range, and
if sufficiently dense, may prevent its operation.
Can LIDAR operate through glass?
No, LIDAR guns cannot obtain readings through
any glass. But the laser pulse can be received
through glass to easily and quickly trigger a laser
detector's alarm.
Can LIDAR operate while moving?
No, since LIDAR is line of sight, an officer cannot
drive, aim,and shoot while driving.
Is a LIDAR DETECTOR legal to use?
Yes,it is legal in all 50 states.
Maintenance
Your COBRA ESD-9100 RADAR/LASER DETECTOR
will give you years of trouble-free service with
minimum maintenance.
Replacing Power Cord Fuse
Unscrew cap of cigarette lighter adapter and
remove fuse. Replace with 1-ampere fuse only.
Troubleshooting
If your COBRA LASER DETECTOR ESD-9100 isn’t
operating, we suggest you make the following
checks:
1. Is the power cord properly connected?
2. Is the fuse OK?
3. Is the cigarette lighter socket clean and free
from corrosion?
