Vehicle (Power Socket)
To power your scanner from a 12V power source in your vehicle, such
as a cigarette-lighter socket, you need a 12V, 600 mA DC cigarette-
lighter adapter (not supplied), available at your local RadioShack
store.
1. Insert the adapter’s barrel plug into the scanner’s DC 13.8V jack.
2. Plug the adapter’s other end into your vehicle’s cigarette lighter
or power socket.
When you use a cigarette-lighter adapter, you might hear
electrical noise from your engine while scanning. This is
normal.
Vehicle (Direct)
1. Disconnect the cable from your vehicle battery’s
negative (-) terminal.
2. Ground the black wire of the supplied DC power cord
to your vehicle’s chassis. The grounding screw must
make complete contact with your vehicle’s metal
frame.
3. Connect the red wire of the supplied DC power cord
to a voltage source that turns on and off with the
ignition switch, such as a spare accessory terminal in
your vehicle’s fuse box.
4. Insert the power cord’s barrel plug into the scanner’s
DC 13.8V jack.
5. Reconnect the cable to your vehicle battery’s negative (-)
terminal.
