22 VISIONEER STROBE XP 300 SCANNER USERS GUIDE
SCANNING ON THE GO
Because the XP 300 can draw power from the computer through the
USB cable, you can use your scanner on an airplane, at a remote job
site, in your car, or anywhere else where an electric outlet is not
available.
Connect the scanner to your laptop with the USB cable. The scanner
will draw its power from the laptop battery.
The Strobe XP 300 also connects to a power outlet. If the laptop
battery is low, or if electric power is available, use the AC Power
Adapter with the laptop.
