Dear Gordon,
I have just found the following and hope it will work for you. If not the right model, let me know and I’ll look for what you need if you let me know. 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. Best wishes, Roger.
