Using Vehicle Battery Power
To power the scanner from your vehicle's cigarette-lighter socket, you
need a DC adapter, such as Cat. No. 270-1560.
Cautions:
• The DC adapter must be capable of delivering 9 volts and at least
300 milliamps, its center tip must be set to negative, and its barrel
plug must correctly fit the scanner's
POWER
jack. The recom-
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).
1. Turn
VOLUME
counterclockwise until it clicks to make sure power
is turned off.
2. Set the DC adapter’s voltage switch to 9V.
3. Connect the adapter’s 3.4 mm outer diameter/1.3 mm inner diam-
eter tip to the adapter’s cord, matching TIP to –.
4. Plug the adapter’s barrel plug into your scanner’s
POWER
jack.
5. Plug the other end of the adapter into your vehicle’s cigarette-
lighter socket.
