and Maintenance
Your Detector
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 widely. 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.
Some common questions about LIDAR include:
Does weather have any affect on LIDAR?
I
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?
I
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 detector.
Can LIDAR operate while in motion?
I
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?
I
Yes. It is legal in all 50 states.

Maintenance of Your Radar Detector
Your detector 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.
I
Make sure the socket of your vehicle's cigarette lighter is clean and
