Congratulations on your purchase of the USB
Bridge from Enhanced Vision. The USB Bridge is
a very useful accessory to be used in conjunction
with your Enhanced Vision product(s). When used
along with the Acrobat™, Flipper™ or Max™, the
USB Bridge provides an all-in-one solution, bringing
both computer connectivity and portability for these
devices.
The USB Bridge serves as a central hub for
connecting your Enhanced Vision product to your
laptop or desktop PC using a standard, USB cable.
Featuring a built-in computer interface and included
software, the USB Bridge allows you to use your
PC while simultaneously viewing magnied, camera
based images on a single display. Built-in software
controls allow you to dynamically re-size the camera’s
display window on your desktop to either full or “split-
screen” modes to best suit your particular viewing
needs. The still-image snapshot feature allows you
to capture magnied, camera-based images on your
PC for later recall, making the USB Bridge an ideal
solution for students and working professionals.
Last but not least, the USB Bridge supplies power
to your Enhanced Vision product via the included
Lithium battery, providing two or more hours of
portable use on a single charge. The built in battery
charger (and included power supply) completes the
package, offering a convenient and fully integrated
“on-the-go” solution for people with low vision.
