4: Hard resetting the Android system: In very serious cases, it may be necessary
to perform a full system reset. However, this should not be attempted unless all
other options have been exhausted, or unless you wish to completely erase all
data, applications and settings. In addition, this process is complex and unique,
and should only be done under the direction of an authorized support staff
member. If you believe a system reset is necessary, please contact technical
support for consultation and full instructions.
16.12 The LCD Does Not Come On
1) If the LCD screen does not come on, make sure that it is turned on. Press
"space-o (dots 1-3-5)" to open "Global Options". Press "F3-F4" twice. Press
"space" to turn the LCD screen option on, and press "enter" to save the option
settings.
16.13 USB or SD Files Seem to Contain 0 Bytes
The Android operating system requires that drives are ejected properly before
removing them. If not done, inserting them in to the BrailleSense or other
devices may result in all files appearing as though they have no data, or have a
size of 0 bytes. Before disconnecting a USB drive or SD card, press
“Backspace-Enter-U” or “Backspace-Enter-3-6” to unmount it properly. If your
drive is showing files with no data, please re-insert it in to the BrailleSense, and
press the Unmount key.
