Connecting Power from Your Vehicle’s Battery

Depending on if your scanner is per- manently installed in your vehicle, you can power it using either the DC pow- er cord or the DC cigarette-lighter power cable (both supplied).

Follow these steps to connect the sup- plied DC power cord.

1.Connect the power cord’s black wire to your vehicle battery’s neg- ative (–) terminal or to a metal part of the vehicle’s frame that is not insulated from the frame by a plastic part.

2.Connect the power cord’s red wire (with in-line fuse) to a source of voltage that turns on and off with the ignition switch, such as a spare accessory terminal in your vehicle’s fuse box.

3.Insert the power cord’s barrel plug into the DC 13.8V jack on the back of the scanner.

To connect the supplied DC cigarette- lighter power cord, insert its barrel plug into the DC 13.8V jack on the back of the scanner, then plug the power cord into your vehicle’s cigarette- lighter socket.

Cautions:

•Unplug the power cord from your vehicle’s cigarette-lighter socket when you turn off the ignition. This prevents vehicle battery drain if you leave the scanner on when you turn off the ignition.

•Always unplug the power cord from your vehicle’s cigarette- lighter socket before you unplug its barrel plug from the scanner.

Note: If the scanner does not operate when you turn it on, remove the power cord from your vehicle’s cigarette- lighter socket and check the socket for debris. Also, check the fuse in the power cord you are using (see “Re- placing the Fuses” on Page 35) and your vehicle’s fuse block.
