need a DC adapter, such as Cat. No. 270-1560.
Cautions:

300 milliamps, its center tip must be set to negative, and its barrel
plug must correctly fit the scanner's
mended adapter meets these specifications. Using an adapter that
does not meet these specifications could damage the scanner or
the adapter.
• To protect your vehicle's electrical system, always plug the adapter
into the scanner before you plug it into your vehicle's cigarette-
lighter socket. Always unplug the adapter from the vehicle's ciga-
rette-lighter socket before you unplug it from the scanner.
• If batteries are installed, make sure
set to the correct position (see "Using Internal Batteries" on
Page 8).
