Cautions:
•The supplied AC adapter supplies 12 volts DC power and delivers 500 milliamps. Its center tip is set to positive, and its plug properly fits the scanner’s DC 12V jack. Using an adapter that does not meet these specifications could damage the scanner or the adapter.
•Be sure to connect the AC adapter to the scanner before you connect it to an AC outlet, and dis- connect the AC adapter from the AC outlet before you disconnect it from the scanner.
Warning: Do not use the AC adapt- er’s polarized plug with an extension cord receptacle unless the blades can be fully inserted to prevent blade ex- posure.
Using Your Vehicle’s Battery Power
If your AC power fails (during an emergency, for example), you can power your scanner from your vehi- cle’s cigarette lighter socket with an optional DC cigarette lighter power ca- ble, such as Cat. No.
To connect an optional DC cigarette lighter power cable, insert its barrel plug into the DC 12V jack on the back of the scanner, then plug the power cable into your vehicle’s cigarette lighter socket.

Cautions:
•If you use a DC cigarette lighter power cable with the scanner, it must supply 12 volts and at least 500 milliamps of DC automotive power. Its center tip must be set to positive, and its plug must cor- rectly fit the DC 12V jack on the back of the scanner. The recom- mended power cable meets these specifications. Using a power cable that does not meet these specifications could damage the scanner or the power cable.
•If you use a cigarette lighter power cable and your vehicle’s engine is running, you might hear electrical noise from the engine while scan- ning. This is normal.
Note: Mobile use of this scanner is unlawful or requires a permit in some areas. Check the laws in your area.
