(1) Revision number indication
When the drive is shipped, the revision number is indicated by deleting the numbers up to the
corresponding number on the line of alphabetic characters. (Each number is deleted with double
lines =. See Figure 6.2.)
(2) Changing the revision number on site
When the revision number is changed on site because of parts replacement or modification, the
new revision number is indicated by circling the number on the line of alphabetic characters. (See
Figure 6.2.)
