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.
