Using Vehicle Battery Power

To power the scanner from your vehicle’s cigarette-lighter socket, you need a DC adapter (Cat. No. 270-1560).

Cautions:

•You must use a DC adapter that supplies 9 volts and delivers at least 200 milliamps. Its center tip must be set to negative, and its plug must correctly fit the scanner’s PWR/DC 9V jack. The recommended adapter meets these specifications. Using an adapter that does not meet these specifications could damage the scanner or the adapter.

•To protect your vehicle’s electrical system, always plug the adapter into the scanner before you plug it into your vehicle’s cigarette-lighter socket. Always unplug the adapter from the vehicle’s cigarette- lighter socket before you unplug it from the scanner.

1.Connect the DC adapter’s supplied 1.3 mm inner diameter/3.4 mm outer diameter barrel plug to the cable, with the tip set to – (negative).

2.Set the adapter’s voltage switch to 9V.

3.Insert the barrel plug into the scanner’s PWR/DC 9V jack.

4.Plug the other end of the adapter into your vehicle’s cigarette-lighter socket.
