Installation Power Connection Power Connection Using the cigarette lighter socket The Cobra SL3 comes with a power cable designed to plug into your vehicles cigarette lighter socket. Take the power cord and plug the smaller end into the DC 12V input socket on the back of the SL3 and the cigarette lighter adapter in your vehicles cigarette lighter socket. DC12V Please Note: Do not leave your SL3 plugged into the cigarette lighter socket when you start your vehicle. The cigarette lighter socket is prone to power surges that may damage your unit. If the device does not power up, please check that the cigarette lighter socket is clean of any debris, remembering not to insert any metal objects into the socket. Check that the cigarette lighter adapter is inserted all the way into the socket and that the fuse in the cigarette lighter adapter is operational. If your SL3 will still not power up, please check that the cigarette lighter in your vehicle is functioning correctly. Replacing the Fuse If the detector stops operating, the fuse in the cigarette lighter plug may be blown. If it has blown, follow these steps to replace it with a 2 amp, 5 x 20mm, fast-acting fuse. Caution: Using a fuse that does not meet these ratings or defeating fuse protection can damage your unit, the power cable, or the vehicles electrical system. 1. Hold the ring near the tip of the cigarette lighter plug, then carefully unscrew the ring by turning it counterclockwise. Nothing Comes Close to a Cobra® 10
