Appendix C: Braille Display Information
Part A: Using a refreshable Braille
display with the ROL
(See Part B of Appendix C for details on supported Braille displays and
information on which control on each particular display corresponds to which
control on the ROL).
Before using your Braille display, if you want to use Grade 2 Braille, you need to
turn this feature on in General Settings as described below. (By default Grade 2
Braille is set to off). Also, if you want to disable word wrapping to allow more
characters per line, you can turn Word Wrap to off in the Settings.
To adjust your settings, start from the Main Menu, scroll to and select Settings.
Next select General Settings. Scroll to and select Grade 2 Braille. Then, scroll to
and select “On.” You will be returned to the Settings menu options. If you want to
turn Word Wrap off, scroll to and select Braille Word Wrap, and then select Off.
Next, connect the Braille display to one of the USB ports on the ROL. Wait 10-
30 seconds for the Braille display to start, depending on your display.
To use a Braille display without adjusting the settings first, power on the ROL
an
d wait until it is fully booted and you hear “Scan and Read,” before connecting
the display. The Braille display should start within 10-30 seconds.
Next, choose the Scan and Read menu option from the Main Menu. To take a
picture, press the Scan button. It will start reading aloud. When scanning a
document using the Scan button on the Braille display, there is no voice output.
If you use the Scan button on the ROL, it will behave as it normally does, but will
stop reading aloud if you scroll the Braille display.
Use the buttons on your Braille display to navigate through the text (read
Appendix C part B for details on your particular display). The cursor will follow
along as you read. The ROL will not, however, read aloud if you are reading the
text using the panning buttons (sometimes called Back and Advance) on the
Braille display.
Please note:
If you are doing a quick check of the battery status by pressing the
Center Daisy Button, and you are using a Braille display, once you press the
Center Daisy Button on the ROL, you can use the Right Roller or equivalent
controls on your Braille display to scroll to the battery status and the Network
Status. Once you have read the status, you can press the Back Button (or
equivalent) to return to the screen you were on.
