Using Vehicle Battery Power

To power the scanner from your vehicle's cigarette-lighter socket, you need a DC adapter, such as Cat. No. 270-1560.

Cautions:

•The DC adapter must be capable of delivering 9 volts and at least 300 milliamps, its center tip must be set to negative, and its barrel plug must correctly fit the scanner's POWER jack. The recom- mended 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 ciga- rette-lighter socket before you unplug it from the scanner.

•If batteries are installed, make sure ALKALINE JACK NI-CDis set to the correct position (see “Using Internal Batteries” on Page 8).

1.Turn VOLUME counterclockwise until it clicks to make sure power is turned off.

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

3.Connect the adapter’s 3.4 mm outer diameter/1.3 mm inner diam- eter tip to the adapter’s cord, matching TIP to –.

4.Plug the adapter’s barrel plug into your scanner’s POWER jack.

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