Connect a disk (such as a compact flash card, SD card or USB
memory stick) to the Braille Sense U2. The disk must have the
upgrade file stored on it. Then, press “Enter” on “Upgrade Braille
Sense U2 Firmware.”

Then, “Upgrade: Online” will appear. Press “Space-4” to go to
the “Upgrade: Offline.” Then, press “Enter.” Then, you will see the
disk list. Press “Space-4” repeatedly to go to the disk that contains
the upgrade file. Then, press “Enter.”

You will then be asked if you want to continue to upgrade. If you
press “Enter” on “No,” the upgrade will be cancelled. Press
“Space” to toggle between “Yes” and “No.” If you press “Enter” on
“Yes,” the Braille Sense U2 will start upgrading. This step will not
appear when your current software version is not the latest version.

The Braille Sense U2 will automatically start the upgrading
process. Please remember that you must not do anything to the

will hear “File manager.”

After you have completed the upgrade, you should check the
software version by pressing “Space-v (dots 1-2-3-6)” while you
