POWER SOURCES

Using AC Power

You can power the scanner using the sup- plied 12V, 500 mA AC adapter.

Cautions:

You must use a Class 2 power

!source that supplies 12V DC and delivers at least 500 mA.

Its center tip must be set to positive and its plug must fit the scanner's

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 dis- connect it from the scanner.

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

1.Insert the AC adapter’s barrel plug into the DC 12V jack on the back of the scan- ner.

2.Plug the adapter’s two-prong plug into a standard AC outlet.

Using Vehicle Battery Power

You can power the scanner from a vehicle’s 12V power source (such as a cigarette-light- er socket) using an optional 12 volt power

cord, and a size D Adaptaplug™ adapter (available at your local RadioShack store).

Cautions:

You must use a power cord

!that supplies 12V DC and delivers at least 500 mA. Its

center tip must be set to positive and its plug must fit the scanner's DC 12V jack. Using an cord that does not meet these specifications could damage the scan- ner or the cord.

Always connect the adapter to the scan- ner before you connect it to the power source. When you finish, disconnect the DC adapter from the power source before you disconnect it from the scan- ner.

Follow these steps to connect a 12V power source.

1.Confirm the adapter’s center tip is set to positive.

2.Insert the adapter’s barrel plug into the DC 12V jack on the back of the scanner.

3.Plug the adapter’s DC plug into the 12V DC power source, such as a vehicle’s cigarette-lighter socket.

Note: If the scanner does not operate prop- erly when you connect a DC adapter, unplug the DC adapter from the power source and clean the socket, or check the adapter’s in- ternal fuse.
