Focus – Display does not respond to inputs such as pressing menu key.
Problem
The Focus does not appear to be responding to inputs by
the user. This problem may be due to the
lock feature for Focus 5th generation.
Detail/Resolution
The Focus Blue 4th and 5th Generation Braille Displays offer a
keyboard locking option that disables the 9 Braille keys (the Perkin-style
keyboard). For example, you could use this lock to prevent losing your place
when inadvertently pressing a key. There is a padlock symbol near the right
side of the Braille display when the keyboard lock is on.
The
Focus Blue 5th Generation also has a control locking feature that locks the 9
Braille keys plus the NavRockers, but does not lock the Cursor Router buttons,
Panning buttons, and Rocker bars. It is not a feature the typical user will
want to turn on. Some call center apps have used this full locking option so
that only traditional keys are used. There is no display that indicates when
this locking feature is on.
Sometimes
a user might inadvertently turn on either of the above locking features and not
know how to unlock it. Steps for locking and unlocking each feature type for
the Focus Blue 4th and 5th Gen Braille displays are given below.
To lock or unlock the 9 Braille keys on a Focus Blue 4th or 5th
Generation Braille display:
- If there are
any active USB or Bluetooth connections, you must place them in the
background. To do this on a Focus 4th Gen, quickly press and release the
power button. To do this on a Focus 5th Gen, press the MENU button once.
The time, battery percentage, charging status, and the active connections
are displayed.
- To lock, press
the Left Nav
Mode button + any Cursor Router button. A symbol shaped
like a closed padlock is displayed near the right end of the Braille
display. This is a two-cell symbol that includes dots 234678 in the first
cell and dots 135678 in the second cell. Focus 14 Blue users will need to
pan forward to see this symbol.
- To unlock,
press the Right
Nav Mode button + any Cursor Router button. The padlock
symbol is no longer displayed.
- Press the Left selector button to
return to the currently active connections.
To lock or unlock the Control lock feature (9 Braille keys plus
NavRockers) on a Focus Blue 5th Generation Braille display:
- To lock, press
the Menu
button + Left Nav Mode button. There is no display
indicator that this lock is on.
- To unlock press
the Menu
button + Right Nav Mode button.
Note: On the Focus 5th
Gen, the keyboard lock can be enabled at the same time as the keyboard and
controls lock. If this is the case, you must unlock the keyboard and controls
lock option first, then unlock the keyboard lock feature.
