Probable Cause
Attempting to begin adjustments on a
digitizer that is secured.
The first character of the security
code must be a letter (A-Z), Numbers
and Underscores may be used
following the letter. Punctuation and
spaces are not allowed.
Only 12 characters are allowed in the
security code.
A remote interface Device Clear
command was received or power was
interrupted during adjustment.
The calibration message string was
lost. Run a full self test to ensure the
digitizer is operational before
attempting to reset.
A gain or offset adjustment failed. Run
a full self test to ensure the digitizer is
operational before attempting to
re-adjust.
The checksum failed for calibration
data. Run a full self test to ensure the
digitizer is operational before
attempting to re-adjust.
