from a Disk
To upgrade the Braille Sense U2 QWERTY Firmware from a disk, follow
these steps:
1) Download the upgrade files from the HIMS, Inc. website. Extract the zip
file and copy the 3 files contained in it to the root of an external storage
device such as an SD card or USB thumb drive.
2) Connect the SD card or USB drive to the Braille Sense U2 QWERTY, and
be sure the Braille Sense U2 QWERTY is connected to AC power. Then,
press "Enter" on "Upgrade Braille Sense U2 QWERTY Firmware" from the
"Utilities" menu.
3) "Upgrade: Online" is displayed. Press “down arrow button” to go to the
"Upgrade: Offline" option. Press "Enter".
4) If you are already running the latest version of the software, you are asked
to continue with the upgrade. If you press "Enter" on "No", the upgrade is
cancelled. Press "Space" to toggle between "Yes" and "No".
5) If you press "Enter" on "Yes", the Braille Sense U2 QWERTY warns you
that all settings will be set to factory defaults, and again, asks if you would
like to continue. Press "Enter" on "Yes".
6) The Braille Sense U2 QWERTY starts the upgrade process. Please
remember you must not touch the Braille Sense U2 QWERTY until the
upgrade is complete. When the upgrade is complete, you are returned to the
"program" menu, and "File manager" is displayed.
7) When the upgrade is complete, check the software version by pressing
"Fn-v" while in the "program" menu.
