Using Vehicle Power
You can power the scanner from a vehicle’s 12V power source (such as a cigarette-lighter socket) using a
9V, 300 mA DC adapter and a size C Adaptaplug (neither supplied). We recommend RadioShack Cat. No.
273-1810 (available at your local RadioShack store).
Cautions:
! You must use a power source that supplies 9V DC and delivers at least 300 mA. Its center tip must be set to
positive and its plug must fit the scanner’s PWR DC 9V jack. Using an adapter that does not meet these
specifications could damage the scanner or the adapter.
. Always connect the DC adapter to the scanner before you connect it to the power source. When you finish,
disconnect the adapter from the power source before you disconnect it from the scanner.
Follow these steps to connect the adapter.
1. Connect the Adaptaplug to the adapter’s cord with the tip set to positive.
2. Plug the adapter’s barrel plug into the scanner’s PWR DC 9V jack.
3. Plug the adapter’s cigarette-lighter plug into your vehicle’s cigarette-lighter socket.

Note: If the scanner does not operate properly when you connect a DC adapter, unplug the DC adapter from
the cigarette-lighter socket and clean the socket to remove ashes and other debris.
