Applying Power for Vehicle InstallationYou can power your scanner using either the supplied DC power cord or your vehicle’scigarette lighter socket using DC cigarette lighter power cord.Caution: You must use a power source that supplies 13.8 V DC and delivers at least700 mA. Your standard 12 V car battery should be sufficient. The cordconnector’s center tip must be set to positive and its plug must fit the scanner’sDC 13.8 V jack. The supplied DC power cord meets these specifications. Using apower cord that does not meet these specifications could damage the scanner orthe adapter.• Always connect the adapter or DC power cord to the scanner before you connect it to thepower source. When you finish, disconnect the adapter or DC power cord from the powersource before you disconnect it from the scanner.• For added safety and to protect your scanner,disconnect the cable from your vehicle battery’snegative (-) terminal before you begin.Follow these steps to connect the supplied DC power cord.1. Connect the power cord’s black wire to a chassis ground, suchas a metal screw attached to a metal part of the vehicle’s frame. Be sure that the screwis not insulated from the frame by a plastic part.2. Connect the power cord’s red wire (with in-line fuse) to a sourceof voltage that turns on and off with the ignition switch, such asa spare accessory terminal in your vehicle’s fuse box.3. Insert the power cord’s barrel plug into the DC 13.8 V jackon the back of the scanner.4. Reconnect the cable to the vehicle battery’s negative (-)terminal.To power the scanner from a vehicle’s 12 V power source(such as a cigarette-lighter socket), you need a cigarette-lighteradapter.To connect an optional DC cigarette-lighter power cable, insertits barrel plug into the DC 13.8 V jack on the back of the scanner, then plug the power cableinto your vehicle’s cigarette lighter socket.Note: If you use a cigarette-lighter power cable and your vehicle’s engine is running, youmight hear electrical noise from the engine while scanning. This is normal.16
