This Operation Guide shows messages of the inch version. When using the metric version, see
the messages of the inch version for reference. With regard to the messages in the text, if a
message has only the difference of upper- and lower-case spelling, we show only the message
of the inch version. When there is even a slight difference in the message, we have listed the
information for the inch version followed, in brackets, by the corresponding information for the
metric version.
