1) 

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.” 

2) 

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.” 

3) 

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. 

4) 

The Braille Sense U2 will automatically start the upgrading 

process. Please remember that you must not do anything to the 
Braille Sense U2 until the upgrade is complete. When the upgrade 
is complete, you will be returned to the “program” menu, and you 
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
