Applying Power for Vehicle Installation
You can power your scanner using the supplied DC cigarette lighter power cord or an DC
power cord.
To power the scanner from a vehicle’s 12V power source (such as a cigarette-lighter
socket), you need a cigarette-lighter adapter.
To connect an DC cigarette-lighter power cable, insert its barrel plug into the
jack on the rear of the scanner, then plug the power cable into your vehicle’s
cigarette lighter socket.
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.
DC 12 V Jack can use a power source that supplies 12V DC at least
500 mA. You must use a power source that supplies 12V DC and delivers at least
500 mA. Your standard 12V car battery should be sufficient. The cord connector’s
center tip must be set to positive and its plug must fit the scanner’s jack.
The supplied DC power cord meets these specifications. Using a power cord that
does not meet these specifications could damage the scanner or the adapter.
Always connect the adapter or DC power cord to the scanner before you connect it to the
power source. When you finish, disconnect the adapter or DC power cord from the
power source before you disconnect it from the scanner.
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 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 insulated
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 jack on
the rear of the scanner.
4. Reconnect the cable to the vehicle battery’s negative (-)
terminal.
