The Focus braille display has built-in diagnostic tests for the cursor
routing buttons, braille display, NAV Rockers, 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 routing 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 button again by itself to exit Diagnostics Mode.
Routing Button Test
The routing button test ensures that each of the cursor routing buttons on
the braille display work properly. Press any cursor routing 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 routing 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.
