• Always connect the adapter or DC
power cord to the scanner before
you connect it to the power
source. When you finish, discon-
nect the adapter or DC power
cord from the power source before
you disconnect it from the scan-
ner.
• For added safety and to protect
your scanner, disconnect the
cable from your vehicle battery’s
negative (
–
) terminal before you
begin.
Follow these steps to connect the sup-
plied DC power cord.
1. Connect the power cord’s black
wire to a chassis ground, such as
a metal screw attached to a metal
part of the vehicle’s frame. Be
sure that the screw is not insu-
lated from the frame by a plastic
part.
2. Connect the power cord’s red wire
(with in-line fuse) to a source of
voltage that turns on and off with
the ignition switch, such as a
spare accessory terminal in your
vehicle’s fuse box.
3. Insert the power cord’s barrel plug
into the
DC 13.8V
jack on the back
of the scanner.
4. Reconnect the cable to the vehi-
cle battery’s negative (
–
) terminal.
To power the scanner from a vehicle’s
12V power source (such as a ciga-
rette-lighter socket), you need a 12V,
500-mA DC cigarette-lighter adapter
(not supplied), available at your local
RadioShack store.
To connect an optional DC cigarette-
lighter power cable, insert its barrel
plug into the
DC 13.8V
jack on the back
of the scanner, then plug the power
cable into your vehicle’s cigarette
lighter socket.
Note:
If you use a cigarette-lighter
power cable and your vehicle’s engine
is running, you might hear electrical
noise from the engine while scanning.
This is normal.
