Maintenance - Cobra RAD 380 Owner's Manual

Unlike radar, LIDAR must have a clear line of sight to its target vehicle throughout the entire
measurement interval. Obstructions such as signposts, utility poles, tree branches, etc., will
prevent valid speed measurement.
Some common questions about LIDAR include:
Does weather have any effect 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 detector.
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 it legal for police to use LIDAR?
Yes, LIDAR is allowed to be used in all 50 States by police. Your detector detects LIDAR (laser).

MAINTENANCE

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.
• 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.
