Using Vehicle Battery Power

To power your scanner from your ve- hicle’s battery power, you need a DC power cord (such as Radio Shack Cat. No. 270-1533).

Cautions:

•Your vehicle must have a 12-volt DC, negative-ground electrical system.

•The recommended DC power cord supplies 12 volts and deliv- ers at least 500 milliamps. The center tip on the barrel plug is set to positive, and the plug properly fits the scanner’s DC 12V jack. Using a DC power cord (or adapter) that does not meet these specifications could dam- age the scanner or the cord (or adapter). The scanner’s display dims if the DC cord (or adapter) you use does not provide the required 12 volts DC.

•Be sure you connect the DC cord to the scanner before you connect it to the vehicle’s ciga- rette-lighter plug. Then discon- nect the cord from the vehicle’s cigarette-lighter plug before you disconnect it from the scanner.

Follow these steps to use vehicle battery power.

1.Insert the barrel plug into the scanner’s DC 12V jack.

2.Plug the other end of the adapter into your vehicle’s ciga- rette-lighter socket.

DC 12V Jack

Note: If the scanner does not oper- ate properly when you use a DC cord (or adapter), unplug the cord (or adapter) from the lighter socket and clean the socket to remove ashes and other debris.
