Your Detector Understanding Radar and Laser and Maintenance 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: I 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. I 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. I 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. I Is LIDAR legal to use? Yes. It is legal in all 50 states. Maintenance • 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: I Make sure the power cord is properly connected. I Make sure the socket of your vehicle's cigarette lighter is clean and free of corrosion. I Make sure the power cord's cigarette lighter adapter is firmly seated in your cigarette lighter. I 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 2-amp fuse only.) 20 English Your Detector Specifications Specifications Band and Frequencies Band Frequencies X Band 10.525 K Band 24.125 Ka Band 34.700 Ku Band 13.435 VG-2 11.500 Laser 910± 50nm 910± 50nm 910± 50nm 910± 50nm 910± 50nm 910± 50nm Spectre I 13.300 Spectre IV/IV+ Safety Alert Traffic Warning System Not Disclosed 24.070 24.110 24.190 24.230 ± 0.050 ± 0.125 ± 1.300 ± 0.035 ± 0.250 100 125 130 200 238 340 ± 0.200 ± 0.010 ± 0.010 ± 0.010 ± 0.010 • GHz GHz GHz GHz GHz PPS PPS PPS PPS PPS PPS GHz GHz GHz GHz GHz This radar detector is covered by one or more of the following U.S. patents: 5,497,148; 5,594,432; 5,612,685; 6,078,279; 6,094,148.
