Below information provides information on how to set and use the input lock on Focus Blue Braille displays.
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.
