power source that sup-
plies 12V DC and deliv-
ers 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, dis-
connect the adapter from AC
power before you disconnect it
from the scanner.
Warning: Do not use the AC adapt-
er's polarized plug with an extension
cord receptacle unless the blades can
be fully inserted to prevent blade ex-
posure.
Using Your Vehicle's Battery
Power
If your AC power fails (during an
emergency, for example), you can
power your scanner from your vehi-
cle's cigarette lighter socket with an
optional DC cigarette lighter power ca-
ble, (not supplied).
To connect an optional DC cigarette
lighter power cable, insert its barrel
plug into the
DC 12V
of the scanner, then plug the power
cable into your vehicle's cigarette
lighter socket.

noise from the engine while scanning.
