Warning: Do not use the AC adapter/charger's polarized
plug with an extension cord, receptacle, or other outlet
unless the blades can be fully inserted to prevent blade
exposure.
Caution: Use only the supplied AC adapter/charger. It is
specifically designed for this scanner.
Using Vehicle Battery Power
To power the scanner from your vehicle's cigarette-light-
er socket, you need a DC cigarette-lighter power cable,
such as Cat. No. 270-031.
Cautions:
The DC cigarette-lighter power cable must be capa-
ble of delivering 12 volts, its center tip must be set to
positive, and its barrel plug must correctly fit the
scanner's
EXT.
PWR
jack. The recommended power
cable meets these specifications. Using a power
cable that does not meet these specifications could
damage the scanner or the power cable.
To protect your vehicle's electrical system, always
plug the power cable into the scanner before you
plug it into your vehicle's cigarette-lighter socket.
Always unplug the power cable from the vehicle's
cigarette-lighter socket before you unplug it from the
scanner.
Insert the DC cigarette-lighter power cable's barrel
plug into the
EXT. PWR
jack, then plug the power
EXT. PWR Jack
cable's other end into your vehicle's cigarette-lighter
.
socket.
