Working in a Secure Environment
Using the Secure Display (Option 006 Only)
• If you have another working instrument, install the board (or boards) into that instrument and
erase the memory. Then reinstall the board (or boards) back into the nonworking instrument and
send it to a repair facility for repair and calibration. If you discover that one or both of the
boards do not function in the working instrument, discard the nonfunctioning board and note on
the repair order that it caused the instrument failure. If the instrument is still under warranty,
you will not be charged for new boards.
For instructions on how to remove and replace boards, refer to the Service Guide.

with the current configuration through the front panel. The display blanks, except for the message
