POWER SOURCES

Using AC Power

You can power the scanner using the supplied 12V, 300mA AC adapter.

Cautions:

You must use a Class 2 power

!source that supplies 12V DC and delivers at least 300 mA.

Its center tip must be set to positive and its plug must fit the scanner's DC12V jack. The supplied adapter meets these specifications. Using an adapter that does not meet these specifications could damage the scanner or the adapter.

•Always connect the AC adapter to the scanner before you connect it to AC power. When you finish, disconnect the adapter from AC power before you disconnect it from the scanner.

Warning: To prevent electric shock, do not use the AC adapter’s polarized plug with an extension cord, receptacle, or other outlet unless you can fully insert the blades to prevent blade exposure.

Follow these steps to power the scanner from a standard AC outlet.

1.Insert the AC adapter’s barrel plug into the DC12V jack on the back of the scanner.

2.Plug the adapter into a standard AC outlet.

Using Vehicle Battery Power

You can power the scanner from a vehicle’s 12V power source (such as cigarette-lighter socket) using a 12V, 300-mA DC cord and a size M Adaptaplug™ connector (neither supplied). Both are available at your local RadioShack store.

Cautions:

You must use a power cord

!that can carry 12V DC and at least 300 mA. Its center tip

must be set to positive and its plug must fit the scanner's DC12V jack. Using an cord that does not meet these specifications could damage the scanner or the cord.

•Always connect the DC cord to the scanner before you connect it to the power source. When you finish, disconnect the cord from the power source before you disconnect it from the scanner.

Follow these steps to power the scanner from a vehicle’s cigarette-lighter socket.

1.Connect the adaptaplug connector to the DC cord so the tip reads positive (+).

2.Insert the DC cord’s barrel plug into the DC12V jack on the back of the scanner.
