Diagnostics Mode
The Focus braille display has built-in diagnostic tests for the Cursor Router
buttons, braille display, NAV Rockers, NAV Mode buttons, braille keys, Panning
buttons, Rocker bars, and Selector buttons.
Before entering Diagnostics Mode, disconnect the Focus from your computer
and make sure it is powered off.
Entering and Exiting Diagnostics Mode
Simultaneously, press the first two
Cursor Router
buttons farthest to the left
(above cells one and two) while pressing the
Power
button. The text, "press cr
key/nav/panel keys," is displayed to indicate that Diagnostics Mode has been
entered.
Press the
Power

Routing Button Test
The routing button test ensures that each of the Cursor Router buttons on the
braille display work properly. Press any
Cursor Router
button to activate all
dots in the cell below the button.
Display Test/Clean
It is necessary to disconnect the Focus Blue from your computer and make
sure it is powered off before beginning this test. The display test is used to
ensure that each pin on the braille display can be activated. The display test
also allows you to clean the braille display. Press the
Power
button while
pressing the rightmost
Cursor Router
buttons (above the last two cells)
simultaneously. This action causes all cells to be activated for cleaning. Use a
soft cloth moistened with isopropyl alcohol. Do not use any other substance to
clean the cells.
While the Focus is in this mode, pressing down on either the
Right
or
Left NAV
Rocker
deactivates all of the cells. Pressing up on either the
Left
or
Right
NAV Rocker
reactivates all cells.
Pressing the
Left
or
Right NAV Mode
button causes the cells to toggle up and
down. To stop this action, press the
NAV Mode
button again.
