The Basics
from your vehicle’s cigarrette lighter
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.
