Error Message Format
Error messages will appear (in the format described below) in the
Status/Info bar that appears at the bottom of the display. Generally the
most recent message will appear, however there are occasions when an
error message that has a higher priority will appear instead of the most
recent one.
Error messages appear in the following format:
<error number><error message><context-specific information><occurrences>
<error number>
(refer to the Error Message Descriptions section)
<error message>
<context-specific information>
about this particular occurrence of the error
- Many repetitive type errors are counted rather than
<occurrences>
being individually logged. Occurrences (enclosed in
parentheses) show the number of times the error has
occurred since the queue was last cleared.
