Locking the Perkins-style Keyboard
When using your Focus Blue in front of your computer’s QWERTY
keyboard, you can lock the Perkins-style keys on the top of the display to
prevent accidentally pressing them and entering unwanted text or
commands.
To lock the Focus Blue keyboard, press the Power button to display the
status information and then simultaneously press a Cursor Router and
the left Mode button. To indicate that the keyboard is locked,
DOTS 2-3-
4-6-7-8
and
DOTS 1-3-5-6-7-8
will be displayed in two cells toward the
right end of the display, just before the connection status. Press any other
control to return to normal operation. Once locked, pressing
DOTS 1
through
8
or the
SPACEBAR
will no longer send keystrokes through to
the computer.
To unlock the keyboard so you can once again enter text or perform
commands from the Focus Blue, press the Power button to display the
status information and then simultaneously press a Cursor Router and
the right Mode button. Press any other control to return to normal
operation and you can once again enter text using the Focus Blue
keyboard.
